1157 front non error LED blinker testing plug and play
 

Now that I have your attention. Stay tuned...I ordered some non error amber bulbs yesterday to test my plug and play theory. I will post up my results after they arrive.

They work now I have upgraded my 91 I am trying to figure out how to get to the 90 bulbs lol. Seriously how do you access the MY 90 bulbs!!!! If anybody is interested in upgrading their amber 1157 turn signals bulbs I have figured it out.

WITHOUT cutting or splicing resisters. True plug and play. The left bulb is a stock amber bulb. The right blub is a LED amber bulb replacement. It does not look like it but the right bulb IS signifcantly brighter. left blinker , right blinker and hazard lights work great. I run the web electrics DRL kit so my turn signals act like DRLs for safety.

I sent -=JEFF=- the video as Imgur does not do videos just img and gifs well....at least I think so... I think. If somebody can host the 8 sec video hit me with an email address and I will sent it to you. GC

Definitely see brighter on passenger side (unless you're in the UK!)

The driver side is brighter it was hard to capture that. You will have to trust me on that. Or not. GC

Do the "error free" leds have resistors built in? I am curious as I would like to do the same thing. Did your turn signals still blink at the correct rate?

Re: 1157 front non error LED blinker testing plug and play
 

Yes and yes. I learned about these bulbs when I was upgrading my wife's Mercedes Benz SLK. It was a 2006 model and had an electronic DIC. You could not just use ANY LED. You have to look for bulb choices that use the words non error or error free. That's LED speak for internally resisted. You still have to watch out what your buying because some EBAY sellers use the words non error but along with the bulbs include standard resistors.

Here's are the style of 1157s I bought (Sealed style) protecting the SMDs from water intrusion (well hopefully) since these are in front and low on the front of the car. These look like the bulbs I bought from the backup lights and shared on the install for the 90. Keep in mind I use an electronic flasher unit not the original mechanical flasher. You will still need one if those for these non error bulbs to work.

The eBay auction I bought these bulbs from was 311910306778. Other manufacturers I'm sure will work as well but basically everything is from China these days anyway. I suggest you buy them in amber vs. white as the bright white LEDs will tend to washout the amber yellow lens on the car. GC

Now that's what I'm talking about. Where did you find one of those. I was able to do this with my motorcycles before. The electronic flasher, if I'm understanding you correctly, makes it so you wouldn't need resistors of any kind for the turn signals with LEDs.
