Lamp Bulb Part Numbers

[jerseydave]

Did some searching, probably wrong key words, looked in FSM and other books but can't find the part numbers for all of the turn signal, brake, rear backup, dash, side marker bulbs, etc...!

I am in the process of rewiring the car and want to replace all of the bulbs as I plug in all of the new wires. I can't read the part numbers on any of the bulbs as I take them off, but I know somewhere on this site there has to be a list.

Thanks in advance!

Could this be what you are looking for, maybe? Found it in the 1968-1973 Opel and GT Parts Book.

Do you still have access to your owner's manual? I know there is a table in there somewhere that lists all the bulb part numbers. I took that to Auto Zone last year and was able to match almost all of them to currently available replacement bulbs.

If You're gonna replace the intrument panel lites get those from OGTS, they're hard to find in the auto parts stores. Here's a list from my Owner's Manual:
Direction light: 1073
Stop light:1157 or 1034
License Plate light: 97
Side Marker light:97
Oil pressure Gage/Warning lights: 1003
Ammeter lights: 1003

Thank you, exactly what I was looking for , guess I'll have to get a parts manual in the near future. I know somewhere I have the owners manual, but that is the only thing I couldn't locate-20 years later where could it be?

Hey Dave:
Glad you're making headway ! While you're at it, consider using the newer, brighter versions of those taillight bulbs, etc. They make a difference - I have them in the Manta

Dave;

For the 5 bulbs you need in the instrument cluster(turn(green), highbeam(blue), brake indicator(red) and headlight rotation indicator(white), you can go to a Saab Dealer and ask for the light bulb for the front cigarette lighter illumination in a '01 9-5. Just ask for 5 of them. It is the same bulb. Old VW busses used the same bulb in their dash. Or you can just order them from OGTS You should also replace all of the bulbs which light up the gauges and such. OGTS has this list too. If there is a parts store which specializes in foreign cars, they should also have these bulbs.

I was at the parts store and noticed that some of the lights have an LED cluster, has anyone tried them out? I think I'll go back with my list later this afternoon and buy what I need so I can put the rear lighting section back together. I will also call OGTS and get the rest of the bulbs ordered!

[namba209]

If you want the LED look for your rear lites, check out the parts review on this site. J.J. Wheatley of DESTEC has an outstanding module that fits inside the lenses for a modern LED look. From folks that have them, say they are brighter than the regular bulbs.

Dave; You were in a GT with L.E.D. Tail lights, MINE!!! If you are ever in PA, I will show them to you. They are the first generation version by DESTEC. They are in my brake and turnsignal lenses. Very Bright. Don't buy the 1157 or 1156 plug in replacements, they are not made for most type of lenses which require a reflector.

Few years ago tried the LED socket bulbs from AutoZone. They would not light in my Opel GT or Chevrolet. Forgot what brand they were?

This site has been referenced a few times for automotive LEDs. Thinking of ordering someday. Haven't priced their S&H charges.

Installed DESTEC LED "wink before blink" brake and turn signal PACKAGE few years ago. WOW!

I just replaced some dash bulbs today, they were easy to get at the local auto parts store, #37 and #53
Then I got curious about using LED replacements bulbs and found this site:
74 37 Instrument Panel Lights for the really small ones and Tail Light Brake Light Turn Signal LED Bulbs for the gauge illumination bulbs. (scroll down, these are long pages)
They come in different colours, but I'm more interested in the brightness and longevity. I know I've read posts which think about dash LEDs, but has anyone actually used these?

www.autolumination.com Tail Light Brake Light Turn Signal LED Bulbs
74 37 Instrument Panel Lights

Thought of using LEDs' to replace my 168/ 194 for Chevy gauge lighting. It was suggested to use 3 bulb LEDs for best indirect lighting.

Looks like the Autolumination Tri-Power 3 LED (#74 bulbs replace the following bulbs:17 18 37 70 73 79 85 86 2721) will not fit into #37 metal bulb holders on GT dash panel. Their single LED may not reflect as much side lighting as a #37 bulb. Would have to look at extra GT dash panel in storage.

Did like their D-Cell 1157 flash brake LED @ $19.99, but already have DESTEC LED set-up. Mercedes Flashing Tail Lights906 Interior Lights

Thanks for the link!

I can't see my dash sufficiently at night, especially the stuff below the radio, there appear to be two bulbs shining on a clear plastic this is supposed to direct light downward onto the heater controls and stuff, one is out the other is pathetically inadequate. I grabbed a cheap $1.50 cigarette lighter powered, three LED in their own little swivel cans and stuck it on the side of the dash board and pointed them where I want them, it is a very cheap and simple (temporary) solution. I'll get a pic if I remember. I'd much rather replace at least the non working bulb and preferably both with brigher LEDs, and also the "courtesy" light above the passenger B pillar, it doesn' throw enough light to do much good, an LED in there might help.
Which bulbs to #37 and #53 replace? Are these numbers universal? Do you have brand name?

#37 replaces the very small bulbs which push into a plastic holder. (These include the two which light up the clear plastic near the cigarette lighter) The ones I bought were 'GE miniature lamps', the originals were Osram.
The #53 are the metal base 'bayonet style BA9s'. I see the website also lists a 'Xenon Super White Natural Glass Bulb' that should be brighter than stock without going to LED.
I believe the numbers are universal.
The #53 glass bulges out a little more than the stock bulbs I had, but they still fit easily. The #37 are a little bigger than the Osrams that came out, but they fit fine and I think are a little brighter.

I have not bought anything from this website, I was hoping somebody else would be the guinea pig. I think this guy lists stuff on ebay as well. I must say the site looks good, there's dimensions and specs for everything... perhaps I will take the plunge.

HTH,

Take out the plastic pieces and clean them, it will help quite a bit. The plastic is used as a conveyor for the light waves, if it is dirty the light waves can be transmitted.

Just replaced all the light bulbs in my GT dash:

Kragen Auto Parts,
(8) Tach/Speedo/Instruments - Sylvania 1983
(2) Dash Lights Below the Radio - Sylvania 2721
(1) Clock Light - who cares, these clocks don't work anyway. But if your clock works I suggest you order through Opel GT Source for this single bulb.

[West Coast GT]

Sockets: the ones holding the Tach/Speedo light bulbs; where does one get replacements? The bezel isn't holding the phenolic insulating disc anymore, and the casing has split.

Source for modern replacements?

[jlthunder]

OGTS has parts like this. Some new, some used. I'm sure there are pleanty of members here who have spares. I'll look in my "junk bin" to see if I have any.

Last night I wrapped the conveyor in aluminum foil and lined the area under it too, trying to seal the thing up to hopefully direct more light to the right places. Also covered some of the open spaces around the metal bulb housing. Hopefully this won't induce a temperature issue. Not sure if helped much as I also replaced the bulbs. I've got the dash cluster on the bench with a battery hooked up to the grounds and the hot to the spare spade on the gray wire cluster up next to the speedo housing. Is this a decent indicator of what it will be like in the car? Or will there be more amps (or watts volts, whatever) when installed in a running vehicle? This also bypasses the dimmer control (which I've shot at with contact cleaner, I'm secretly hoping that cleaning it will up the available voltage too). I'm trying to optimize my lighting on the bench to be able to decide if I've got it good enough or if I have to try to re-work something.

Jeff, I noticed that the Manta and Ascona dash light conduits were chromed. I'm assuming to help with the light transmission. Try some plastic chrome paint and mask off where the light is supposed to be emitted from before painting.

That's a good idea, chromish paint. I thought about reflective tape (duct tape) too but didn't feel like running out and getting any. I also wanted to fill in some gaps between the mounting bracket and such, maybe those gaps were intentional for heat dissipation but I covered some of 'em anyway. Guess I'll know if it helped when it's all back in the car. Before I couldn't even tell there was light there at all, very faint glow, so anything should help. Do wonder if that reostat dimmer has been holding back some trons. It was either off or on with very little if anything in dddddddbetween in terms of brightness.

[hrcollinsjr]

It's amazing how much just cleaning all that stuff helps and that includes the lettering/symbols on the rocker switches as well.

I tried Dupli-Color Chrome, spray paint, but wasn't impressed with chrome look. Finish looked like high quality silver paint, but not chrome. Finish is better than corroded plastic.
