Interesting question I guess, But since I have my gauge cluster out for clean up and repairs/replacement components
I figured I would go ahead and replace all the bulbs with new ones.
I found it interesting that I could/can find all the bulbs BUT the ba9s bulbs are 1.7 watts as apposed to the original 2 watt bulbs?
I know these things aren't very bright to begin with but how much difference is it really to be off by 0.3 watts ?
Also I found 3 watt bulbs BUT once I looked closer at the specs the 3 watt life expectancy is 800 something hours where as the 1.7 watt bulbs are good for 2100 hours???

Why would you want an inferior bulb? LED is brighter and lasts a lot longer. Unless you don’t actually care about seeing your gauges at night. The only reason I could see wanting a filament bulb is for originality but that’s also accepting all the flaws too for the sake of originality.

I think he was having problems with the housings the Leds went in. I may be wrong. Just pointing out the longevity of the originals. True, the Leds will be brighter and a excellent upgrade.

VDO actually supplies LEDs for their gauges. They have the blade type and the large round ones. VDO has used the same size bulbs for decades. I think they still provide the filament bulbs too.

The chances of me driving at night are slim to none,
I thought I read the use of led's meant making adjustments to the gauge opening or drilling/cutting out the plastic for them to fit.
Also I read that they don't work well with the dimmer switch?
Besides that the cost to go all led in the gauges verse standard bulbs is a little ridiculous considering I won't be driving at night for 1 and 2 when I do night drive in my other vehicles I usually have the interior lights off or as dim as I can get them

Not really driving at night, then I wouldn’t worry about LEDs except for your indicators, brakes, and reverse lights. If you want to drive a GT at night, then I’d go for all LEDs.
