Gauging interest for group buy, LED tail lights

I have an mfg. direct order together for a set of rear tail light LEDs. 3W Lux, with 11 SMT on the side, available in 1156 and 1157.Link here for reference
Others who have used this are more than welcome to post comment on there results. I am happy with the one I tested in my '84.
So, I'm using a poll to gauge interest from people who would like to go in on the order with me. This is just for tail light bulbs, which mean 5 1156's for pre-87, and 5 1156's and 2 1157's for 87-later. This includes the 3rd brake light.
Pricing is prelim and may drop depending on the quantity. Somewhere between $10-12 ea. is my best estimate.
I'm only interested in tail lights.

On the OB's, would these replace all four bulbs in back?

How have you addressed the bulb monitoring warning?

FWIW, after having tried the ones you pictured on my '90 S4, I wound up getting the latest and greatest "115n-c45T"-family 1156/1157s LEDs from superbrightleds.com:

See another one of my posts for my full list of recommended LED bulbs for exterior applications on S4/GT/GTS cars.
The problems I had with the ones you had pictured were twofold:

The problems I had with the ones you had pictured were twofold:
- not quite bright enough when brake light on
- too bright with just parking lights on (in fact, while I was running these, I actually put tape over the parking light contact, because it was too difficult to distinguish between the parking light state and the full brake light state)

The question I don't know the answer to is:
Since the bulb monitor senses a current draw imbalance between left and right sides, would these 3.5watt LED draw enough power equally to NOT fault the bulb monitor?

Damn Ed,
Thats some bulb collection
What do your 5 LED bulbs cost?
I would be interested if the per unit cost was less, think $4 per bulb. I am not paying $10 x 12 for tail lamp bulbs. Am i understanding this correctly that its $10-$12 per bulb?

Wow Ed! That is an extensive collection of LED lamps. It appears with Ed's testing, the combination I've offered for the 87-later may not be the best choice.
I would say it's still a good choice for the pre-87. Though most likely not as bright and the new style 5 watt (1157-RLX5).
I can't find an asian source for those and if anyone finds a lead, let me know. They are $30 each retail.
Thanks Ed.![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)

I'm now using:
- superbrightleds.com 1156-RLX5 for left and right rear turn signal (you'd need 1156-ALX5 if you have amber turn signals; I've painted mine red)
- superbrightleds.com 1157-RLX5 for left and right rear brake/park
- superbrightleds.com 1156-RLX3 for center brake (I'd recommend an 1157-RLX5, instead, though; they just weren't available when I first put this in and I haven't gotten around to upgrading this yet)
- superbrightleds.com 15-LED 67-R15 for left and right rear park
- superbrightleds.com 15-LED 67-R15 for rear side markers
- superbrightleds.com 15-LED 67-A15 for front side markers
- autolumination.com "1157 dual-circuit Tower II 20 LED" amber for front left and right turn signal / park (I'd still like to get these brighter)
- not quite bright enough when brake light on
- too bright with just parking lights on (in fact, while I was running these, I actually put tape over the parking light contact, because it was too difficult to distinguish between the parking light state and the full brake light state)

$10-12 each. They retail at $20-25. Minimizing cost is how this got started. I've asked my source what is the next quantity price break.

Ive got LED's in both tail lights and brake lights, I really like 'em. The brake lights I installed 3w lux, in the tail lights I used 1w lux.,of course my car is an OB.

Well, I tried to edit the poll to change the criteria. I searched everywhere and couldn't figure out how. Anyone have a solution? PM me.

IMHO, before you commit to anything, you might want to get a few samples yourself and try them out. Things to look out for:
- overall brightness
- if 1157 (two circuit) style, relative brightness of the two intensity levels
- beam pattern
- brightness relative to other bulbs (especially true for taillight assembly)
- build quality (some of the bulbs I've seen seem to be really cheaply made)
- you get a batch of LEDs and install them
- you view the results and, to be honest, are a little disappointed by one of the criteria I gave above (it's really not as bright as it should be, it doesn't fill out the lens uniformly with light, etc.)
- you rationalize and fool yourself into thinking it's OK after all and leave substandard lighting in place (or get discouraged and put back the incandescent bulbs)
- new products appear and you go through the cycle again, discovering that things are better, but maybe still not good enough
- build some kind of diffusers for the 4 parking light LEDs (the 15-LED 67-R15 units) because they don't produce uniform-enough lighting over the lens and they're a little bit too bright compared to the adjacent brake/parking light (when it's in the parking light state)
- possibly try the 1157-ALX5 for the front left and right turn/parking lights (I've got my doubts about that, given the shape of the reflector and lens, but I might try it anyway).
- get out my light meter and camera and actually do A/B comparisons between the original incandescent lights and the LED replacments
That said, I'm happy with my brake lighting now (plus, I've also got a LED strip under my rear wing, so there's a pretty good light show when I hit the brakes). The rear turn signals don't fill out the lens very well, but that was actually true (to a lesser extent) with the incandescent bulbs in there, too.
Finally, when you're testing your setup, whatever you wind up doing, make sure you look at it on a bright, sunny day. What looks cool and adequate at night or on a cloudy day can be completely washed out on a bright, sunny day.
