I switched over my turn signals and tail lights over to LED's so far.
They sure last allot longer and don't melt the contacts either because they run cool......

Ted, I am an automotive lighting and safety consultant. Please go get those LED bulbs out of your car in a big hurry — like before you drive it again. They are extremely unsafe to you and those you share the roads with. LED bulbs like this don't perform safely in lamps designed to take bulbs. Please see this thread for more info, this Allpar page for a comparison of LED bulbs like yours vs. brighter filament bulbs, and this thread for more discussion on how LEDs might be retrofitted safely and effectively to your car.

If you want to customise or upgrade any of the lights on your car, there are plenty of options for doing so in ways that give a real improvement in function, and there are even ways of doing it that give various different kinds of improvement (or at least change) in appearance. You can easily and cheaply do some plain old maintenance that'll improve the existing lights' function. You can have better headlights, brighter signals, LED marker lights, you can add daytime running lights, an LED center 3rd brake light, you can get custom lenses that give you separate red brake/tail and amber rear turn signal lenses...lots of options for doing it the right (safe, effective) way; please don't do it the wrong way. Please go get those LEDs out of the lights on your car. They really are a serious crash hazard, and we'd rather have you around here for a long time so you and I can keep arguing about aluminum intakes and stuff.

Dan,

Thanks for the heads up!

Are you ok with the 39 LED type 1157's? If not, let me know.
They seem to put out allot more side light compared to the 24 LED style.

Yeah, that darn aluminum one barrel manifold was a real help to the mileage gain on my SL6. So was modifying the 1920 Economaster, drilling out the plugged off idle air bleed. Getting the emulsion circuit working was a big help. Those two items got me from 22.5 average to over 25 mpg. That is pretty good for the way I drive.
I wonder what the Super Six mod will produce in terms of mileage?

Doesn't matter how many emitters are on the "LED bulb". The problem is with the concept, not the implementation. Please put back the right kind of light source for these lamps, which is a filament bulb. You can use regular ones or carefully-picked high-output ones per the links given above, but "LED bulbs" just really cannot be made to work safely in brake and signal lights meant to take filament bulbs.

i believe the reason is that they do not broadcast light in the 270* sweep of incandescent bulbs and thus do not take full advantage of reflector design.

That's the main crux of the matter, but even the fancy "LED bulbs" that have a tower or cone of emitters facing sideways don't get the job done. Lamps meant to take a filament bulb have optics that are looking for one emitter of light evenly in all directions, located at the focal point. Nothing else works.

Be awesome if there were actual taillight assemblies that looked factory but were designed for LED lighting.
As it is, I'd go with regular bulbs after reading the research Dan has done on the subject.

A guy can hope, I guess

Know how they always build a better idiot? That's me

there companies that make light s like that but they are for chevys and ford and late model cars/trucks. i was considering building my own LED taillights with small led for the running lights and bigger, brighter ones for the brake lights. needless to say, that project never got out of my head.
