I need to replace the bulbs that light up the PONTIAC on my 88GT. Does anyone know the bulb #?

its the same bulbs that are used as back lights in your dash!!!!! i just foudn this out yesterday as i had to dissasemble my tail lights :-)

They take #194 bulbs, real easy to change I just changed some of mine.

You can upgrade it with brighter bulbs. I don't know the part number but Rodney Dickman sells them.

I recently replaced the bulds is illuminate the "PONTIAC" with superbirght LEDs. The signage is now brighter, less heat. In fact, I went ahead and replaced all my instrument cluster lights and other interior lights.

Personally, I very satisfied with the results.

Cajun,

Any chance you have a link or part numbers to do what you did? Sounds like a good mod.

yeah, sounds good, link us to the bulb upgrade.. wouldnt mind brighter dash lights myself.

Cajun, I too would love to get a little more details on what you did.
Part numbers and the supplier would be great.

Oh, yeah, any before and after pics?
Thanks.

Okay, guys here you go: http://www.superbrightleds.com/


Enter the site, go to the Automotive section. On the site is buld cross-reference information but in most cases the intended buld replacement information is located with the LED buld replacement information. In most cases, the prices are not bad either.

Brightest standard bulb that doesn't get too hot is part # 904. Very common and cheap at any auto parts place. Have been using them for years without one burning out

Actually they don't. The GT tails are the same as the dome light. A 906 style bulb. Same base as the 194's but a larger bulb with a higher wattage. 10-12 watts is perfect for a little brighter. IIRC 9W is stock.

The 194's are a 3w bulb and not nearly bright enough to light up the tails properly IMO. 168's are a 5w version of the same bulb. All wattages are quoted at 12V.

EDIT: Here is a decent guide to replacement bulbs... of course it doesn't list the "pontiac" though.

According to GM (Mitchell on demand) and what was in my car they are 194 bulbs I only replaced a couple and they all look the same at night.

I had this text doc. in my Fiero Folder... hope it helps.

Brighter "P O N T I A C" taillights
Using brighter bulbs - 86-88 GTs only
I've been told I can use bulb #921, which is twice as bright
as the standard bulbs to make it more readable.
One of my Pontiac Emblem lights burned out... or so I thought, until I pulled it out. The socket was melted. In fact, all four sockets were deformed. There are 921s in my car that must have been put there by the previous owner. I'd be careful about replacing the standard lamps with a higher wattage.
As a matter of fact, let me pull out my 'GE Lighting Miniature & Sealed Beam Lamp Catalog'...
The 921 is a T5 wedge base lamp. The 'T5' signifies a tubing diameter of 5/8" (5 X 1/8"). It runs on 12.8 volts and consumes 1.40 amps (WOW!). It delivers approximately 21 mean spherical candlepower (don't worry about this, just remember the higher the number, the brighter the lamp output) and is rated for 500 hours of operation. So, the total wattage for four lamps is over 70W, which is more than a high beam filament! Now I'm starting to worry about my ignition switch.
The standard 194 lamp is a T3-1/4 (about .40" dia.), consumes .27A @ 14V, delivers 2 mean spherical candlepower (MSC) and should last 2500 hours. The 168 is also a T3-1/4 lamp, consumes .35A @ 14V, delivers 3 MSC and has a life rating of 1500 hours.
To make the emblem brighter, you need to match the wedge base, operating volts, and increase the MSC. Here are some other T5 suggestions:
Lamp Volts Amps MSC Life (hours)
904 13.5 0.69 4 5000
906 13.0 0.69 6 1000
912 12.8 1.00 12 1000
916 13.5 0.54 2 10000 (not brighter, but will last forever)
917 12.8 1.20 10 1200
918 12.8 0.56 6.5 500
923 12.8 0.91 12.5 500 (a good compromise?)
There are others, but the life or MSC is less than the standard lamp. The 912, 917 and 923 might be good choices because they increase the light output considerably, and don't run as hot as the 921. With this information, you can make a choice that best fits your needs.

Thanks for the info on the bulbs... Love that hurricane license plate.

I never understood why people hide their license plate on the internet. You drive with it displayed in public every day why hide it here? Only the police or people with a need to know can access the license plate database so it's not like you are giving anything away. To prove my point I have the brighter bulbs in my "PONTIAC" lights
