DIY LED Tail Light Bulb Swap

[GilliamOS]

So the clear section on the outer lamps is only for reversing? On the sedan it comes on when brakin and signaling.

Yup, reverse only. It's a plain 194 bulb in there.

On the RoW model, the clear section is at the corner for signaling (yellow), and the inner part is for reversing (clear).

Are you sure no one has played with the coding before? You should try:

207 Signal left - 70
208 Signal right - 102

This will enable the clear portion (there should be a red lens) for signal/braking.

No way, this car was completely stock and factory when I bought it.

If there is a red lens, it's well hidden in there. Here's a high res shot of the rear end where you can see all the bulbs. At my lunch, I'll go to my car and try the coding you suggest for 207 and 208. I am really curious about all this.

I wish US had amber blinkers. I dislike the red for signaling.

Okay, the results are in: Subtracting 3 from both the channels makes no change to the clear portion my lamps. Instead, it enables the rear fogs to come on with braking and signaling, but at the expense of the rear fog light function. The switch will light up amber, but will not actually turn the lamps on. I went back to 73 and 105 respectively.

[STA4]

So, 200, 201, 207 and 208 all control fogs?

[GilliamOS]

So, 200, 201, 207 and 208 all control fogs?

Unsure about 200 and 201, they have remained zero and I have not touched them. but 207 and 208 def change their behavior.

Okay, here's my final suggestion:

200 -> 70
201 -> 102

It seems that NA and RoW coding isn't the same.

No change at all using those codes, so here's my final coding chart:

195 Left middle - 14849
196 Right middle - 14881
197 Left outer - 13320
198 Right outer - 13352
199
200 Fog left (only Avant) - 0
201 Fog right (only Avant) - 0
202
203 Left inner (on Limo also Fog) - 14849
204 Right inner (on Limo also Fog) - 14881
205 Reverse left - 13
206 Reverse right - 45
207 Signal left - 73 - (Subtract 3 to enable rear fog for braking/signaling)
208 Signal right - 105 - (Subtract 3 to enable rear fog for braking/signaling)

Thanks. Now help us find some bright red 1156 / BA15S LED bulbs.

Do these not make the cut? I was going to buy them, as I've bought all my LEDs from SB and had good, long lasting bulbs. Then I was going to use these for the reverse lights.

I find them to be a ripoff. I have the white version of those (bought on eBay for $5/each) and they're 540 lumens. The red ones are only 130 lumens, which will be dimmer than halogen (460 lumens).

I bought a set of CANBUS reverse LEDs for a little less on eBay as well. Note that CANBUS isn't required now that we know how to disable the errors.

CANBUS to bulbs only serves to check for working bulbs, and not brightness too? Did not know that! I guess my hunt continues for good LED bulbs then, glad I didn't buy the SB version. I felt the price was a bit high too, but at 1/10th the cost of OE LED tails, they're still a "bargain".

[GilliamOS]

These bulbs look hilarious to me. Too bad they're 1157's.

[Lambda13]

I just ordered these for my reverse lights and installed them yesterday, no lights on the dash and they work great!

I ordered 10 CAN-BUS bulbs direct from China for $18, identical to what SuperBight sells. I'd say those USP's are horrendously overpriced.

Yeah... I got the same ones for $18 free shipping.

And also the red LEDs I bought for my fogs look amazing... No error codes

Oh well, I got several other things as well and I wanted to make sure I had no warning lights on the dash.

Those arrived fast. How's the brightness?

[Carlos74]

I actually installed them a couple days ago and I was waiting to see if any error code would pop up but so far so good. The brightness is exactly as the corner LEDs I have on my tail lights. No pinkish color at all. They look pretty darn good!!

[STA4]

Finally had my tails coded with the white LEDs. Will use these until I find a bright red bulb.

Yeah, good luck with that. I've been searching high and low across the web with nothing to show for it. Even the little 194 CANBUS bulbs I tried in the brake light position made the output too pinkish for my liking.

[Jmstrag]

I couldn't handle the pinkish colour using the white, the brightness was perfect though :(

I recently ordered a new set of red leds to try out, I hope they will be bright enough but I'm not holding my breath. I will let you guys know how they look when I get them

[Iridium.]

Any word on a better bulb? I dug through SuperBrightLED's 1156 CANBUS option. The red output is listed in the table below.



I'm going to assume most 5050 LED applications are going to be in this range and I've yet to see a good 5630 option available.

130 lm isn't shit sadly. Way too dim for a critical application like brake lights.

[MatZo]

I am still getting bulb out errors on mine, even after going in to disabling them. It looks like it works when I overwrite the code but then when I press the brake again the error comes back.

Post your adaptation codes.

I need help please I need to get rid of the bulb out warning and also the fog like needs only to be a fog light currently is on with the rest of the lights thanx to all

I assume you tried the coding for the OEM halogens. If so, add 2 to the values in channel 203 and 204 to restore it back.

Others with those lights haven't complained about bulb out warnings, so that's a surprise. Here's the chart once again for channels 191 and 192:

The use of the channels are not the same on the facelift - so the best would be to see the current codings.

Those aren't facelift taillights, they're aftermarket on a B8.

OK - you have a point :)

They are wired the same way as the OEM LEDs ??

There are two models, one for OEM halogen and one for OEM LED. They're plug and play.

Unfortunately these tails are for the own led b8 but I did the wire pin swap

Your coding is correct. I think you bought the wrong taillights. If you have halogen tails, then you need the taillights for halogen. They have modules to prevent bulb out warnings.

[softcheeksprod]

Yes I did but these were the only ones they had at the time

Is there a way to code it with them being for oem led's
