Jim - I actually think having brake lights with a combination of incandescnet and LED responses yields the most visibly noticeable effect. If you wanted more visibility still a partially pulsing center brake light (just a few times each time the brake is activated - with timeout) gets even more attention.

There are so many cars with all LED rear lighting now that the faster response seems to have less effect on its own - just like how center brake lights helped until everyone had them and got used to them...

To me incandescents really work very very well - are reliable - and when they do blow the car will tell me!... hard to beat

Maybe your special $20 bulbs work as well - but thats a heck of a lot more $$ than a dual filament incandescent. What are you doing about the bulb monitoring for the brake lights?

LEDs sure do keep getting better though - and on new cars that does/will yield great new lights - retro-fitting is always much more of a compromise.

Alan,
I agree with most of what you wrote. The center brake may "seem" passe, but it works well. A triangle has more depth than a straight line.

And I definitely can't argue cost; LED vs. Incand. What it is to me is a project to dink around with in between big projects. It help me maintain interest in getting my hands dirty.

To fix tirggering the lamp bulb warning, I will do the resistor and jumper fix that Borland used.

I've got lopsided brake lights.
One 3W luxeon multi bulby light in the right brake light. You get a bright spot in the center of the lens as the "reflector" isn't optimized for LED, even with the multi-bulb array.
But with 2 ancient tech incandescent bulbs (center and left bulb) in the brake circuit, the brake bulb out warning does not light up.
I pulse my brake pedal lots of time when I slow down or stop so it must look real wierd have the 3 lights go on off on off.

On the other hand the 1156 LED multi array bulbs I put into the rear light cluster seem to work pretty well. I put in red LED's and they seem pretty bright. Haven't disabled the tail cluster warning system yet.

What is the difference? I'm confused...

What LEDs are you using for the front corners? I have the clear lenses there, and thought LED bulbs would get rid of the yellow bulb that's visible in the clear lens now. I know some people have painted the stock yellow bulbs with silver paint to try eliminate that yellow bulb look, but I personally don't like that solution.

Jim D,
The 1157 LED's are for the multi-filament brake/park bulbs.

The 1156 LED replaces the single filament rear parking light bulbs.

Ernest,
Got it, thanks. I forgot the S4 used 1157's

I'll post to a new thread....

So did I once. All Hell breaks loose when you put 1156s in there. The tailights blow fuses, the sidemarkers start flashing with the turn signals (kinda cool).
