Hey guys, so I got a full housing LED setup to replace my oem yellow rear plate lights.

No errors from the LED's but they FLICKER and strobe during startup.


Are they any LED plate lights that don't strobe? Or even just drop in bulbs like festoon bulbs that don't flicker?

Thanks!

Every LED, whether it be Can-Bus, Error Free, etc - will flicker & strobe.

This is due to the Bulb Checks (Cold & Warm). Car system shoots a low voltage to all the exterior lights @ startup, and later when warm, to check for burned out bulbs.

The voltage is low enough to not light up the OEM bulbs, but LED's need very little voltage to light - so the bulb check voltage sent across the system causes any LED to flicker or strobe.

Long story short - only way to get rid of the LED flickering is to code out the Cold/Warm bulb checks using NCSExpert software & coding cable as described in great detail in the Coding Section of the forum.

Dealer can NOT code out individual items such as this so no need to even ask them...

AHH gotcha! Thanks a lot for that informative post.

Coding out the cold/warm bulb check, specific to plate lights, or is it a overall coding shutoff?
