Re: License plate LED bulb upgrade
I think a resistor across the positive and negative for the turn circuit on the 1157 will correct the issues

I took a look at my 91 wiring this evening, and I see what you mean about the dual-side use of 12V. It's another example of how GM used bulb filaments for circuit control, a little like what they did with the fog light disable when switching from low to hi beam. I see how a couple of relays could solve the switch to LEDs for the front signals and side markers. I'll have to sleep on it - just did a relay mod to address the issue I had with fitting the HID fog lamps and need to tackle some other (non Zee) things on my to-do list before getting the wire strippers out again.

Re: License plate LED bulb upgrade
GOLDCYLON, I can't seem to find the thread that talked about 'plug-n-play' success on the LED turn signal lights... I thought there was another thread besides this one.
In any case, I had ordered the aforementioned amber LED bulbs on ebay, from seller "summermotors86". They are titled: 2x Amber No Error Super Bright 30Watt 1157 BAY15D XBD LED Brake Light 12-24V Along with installing those two front turn signal LED bulbs, I ordered and installed the CEC Industries EF32 Electronic Turn Signal Flasher from Amazon. I have no other LED bulbs other than the two front turn signal/parking light bulbs. All works great on the '94 Z. Parking lights on - amber is bright, not overly bright. Turn signals work front (LEDs), side marker (stock bulbs) and rear (stock bulbs) at a normal rate with a pleasant 'clicker' the same rate as stock. With or without the headlights on, all works normally. I like 'em! Thanks for the help. "G"

Re: License plate LED bulb upgrade
I soft deleted that post while I was working on a problem with the mod. While everything appeared to work correctly the next day I ran into a problem when the park lights are on or the headlights are on as the blinkers will error out. The solution was to pull the amber turn signal bulbs from the front side markers. It appears GM runs 12v power through the side marker connections while pulling a 12v load to power the headlights. I asked -=JEFF=- to work a plug and play solution for me as I did not want to splice resisters into the factory wiring. I paid for the hardware for him to bench test and research for me. He did create a plug and play solution for me and I am ordering two more kits in the future. I have been running the plug and play mod now for three weeks with no blinker errors to date and I have replaced both my front and rear side markers with amber and red LEDs. I will activate that other post this weekend as I have a few pics to make of the install. Do me a favor since I have a 90 and a 91 only will you turn on your headlights and see if your turn signals work? I believe all C4s MY 90-96 are wired the same way. Thanks GC
Please note this mod is not ready for prime time and is in the trials and bench test mode only. -=JEFF=- will announce if and when he is ready to start making this plug and play mod available to the C4 community and at a price point of his choosing. This is Jeffs innovation and we are darn lucky to have him in the community. Jeff was kind enough to take his time to find a PNP solution for me that may benefit the entire community in the future. Just like Jerry, Cliff and a few others I'm sure I missed. We have an opportunity to advance our hobby and this great organization. GC

Re: License plate LED bulb upgrade
Thanks for the kind words GC.. I am out of commission for 6 weeks and will be able to start back up after. By thne it will be cool enough for GC to get pictures and some measurements I need for me to continue. He will then get 2 more sets to mess with
Then I can figure out how well they will work

Glad to help in any way I can... I have tested the front turn signal LEDs at both the parking light setting and with the headlights on at two different times yesterday, while driving around and parked. They work flawlessly. The only thing I notice, is that with only the parking light setting ON, the green turn signal arrows above the Speedo light up dimly (I didn't notice that before, maybe it did it before the LEDs). But when activating the turn signal, they light up brightly in the direction of turn. ... I'll keep testing them this week, and let you know if anything changes. I can dropbox you a video of them working, if desired. I also took some pics of the DIY process and would be glad to post when you guys are ready. When looking for bulbs for any of the exterior lights, I do notice a difference between the 90 and the 91-96 fixtures and some bulbs. Also, with the base model Vette going from the L98 to the LT-1 in '92, makes me wonder if there was a change in the electrical system in there somewhere. ?? Absolutely, appreciate Jeff and all those who take the time to dig deeper into all the things that make our machines run great!

Re: License plate LED bulb upgrade
Yeah so mine did the same but one inside arrow was bright. It should not do that. It is a combination of bulbs wiring resistance and a few others things.
