Dear Ferraristi, Do you know how embarassing it is to have a bulb burned out on the TR? I was so consious of it. Eveytime I was at a stop light, I was thinking about the guy/gal behind me thinking " look at that moron, he's got a Ferrari, but doesn't care about the maintaince....poser ! " I have checked everywhere with no luck. Ferrari will only sell you a new 3rd brakelight assembly for $400.00 I checked Napa, Walmart, Discount Auto, Advance, Pep Boys and even GM dealers ( the light assembly has a GM part #) with no luck ( part # comes up not available in GM's computers ) I even check out a few on-line light companys recommended by F chat links. .....no luck. After 2 threads and 1 1/2 years of searching, I have FINALLY FOUND the bulb that goes in the third brake light in a Testarossa. OK, here it is.....GE Automotive Lighting Halogen 12V 891/BP Stop, Fog $6.91 I found it at .....ready? Walmart. Yes, yes, I said I checked at Walmart before. I would just keep checking everywhere all the time. They must have just started carrying it. I actually found it by chance. The bulb in the TR doesn't have any stampings on it, so you can't match it. I saw this one, hmmm...kinda looks like it...two prongs, small glass , same shape, ok, I'll try it. It matched in size to the blown one...ok, I'm getting excited...keep calm...I bet the luminance value is off, it says halogen on the package....halogen for a brakelight?!? I put it in, turn the assembly towards the rear window under the engine cover.....hit the brakes....Voila ! YEAH...BABY, YEAH !!! Even fully assembled, in the dark, it is a perfect match. I would have never thought that the bulb would be a halogen. Now, anyone got a line on the white plastic bulb holders in the TR? One of the plastic "twist-locks" that goes inside of the light unit broke off. Shamile Freeze...Miami Vice !
Yeah those rear light sockets are impossible to find. My first TR had many of these sockets broken. I looked all over and finally gave up. The only way you can get the sockets is to buy the entire light assembly - and that's big bucks! I finally found a GM light socket that would twist into the TR's tail light housings, bought a bunch of them and wired them in place of the factory sockets. It worked great and of course the light bulbs are the usual domestic ones too.
Yeah, who designed those huge and fragile twist lock holders, anyway? - I'd like to smack a gold star right on his forehead.
