R/C/R LED brake light problem

Well I just got done installing my LED R/C/R taillights and they look sick but I noticed when I press the brake pedal, the driver's side brake light comes on a fraction of a second quicker than the passenger's side. While it's not a HUGE deal, it does bug be enough to fix it.

I am currently waiting for resistors to fix the bulb out indicator, could this solve the problem?

I just installed the exact same tail lights on Saturday, and I noticed the same thing. Please let me know if you find a fix for this problem.

^ Do you have the resistors installed yet?

Oh, and if you have the trunk lights, follow these instructions to dim them to match the running lights:

^ I don't have the resistors installed yet -- thanks for the link to your post, that's great info.

I do have the trunk light LED's, but I don't have them hooked up yet. I see there is a red and black wire coming from the LED Circuit Board and going to a plug, but I didn't see anywhere to connect this plug to. I figured I'd have to tap into the license plate lights, but honestly I couldn't figure out how. What type of connector did you use to go from the license plate lights to the trunk light LEDs, and which wire did you tap into from the LED Circuit Board (red, or black)?

Thanks for your help, I really appreciate it.

BTW, these lights are awesome.

I tapped into the license plate lights for the LED trunk lights. They work great, but the only downside is that they flash every 60 seconds with the 'test' signal sent out by the LCU (only if the lights are switched to 'off'). I'm going to re-route the power wire to the rear tail lights instead since they don't do the 1 minute blink.

My trunk lights came with a bulb harness end on it...so I ran down to the junkyard and cut off a bulb carrier with a few inches of wire to install.

^ Do you remember which wire is power and which wire is ground running to the license plate bulbs? I'm going to give it shot and see if I can hook up the trunk light LED's as you did.

Also, did you have any luck running the connections down to the tail lights vs. the license plate lights? I don't really see an easy way to do that without the wires showing.
