Thread: Alternating/Sequential Taillights [*]

This writeup on Sequential Tail Light Modification has been added to the How To section and can be found HERE.

I'm almost regretting inventing this mod, as it MAY wreak havoc with your LED lamps (if you have them) and digital HVAC (if you have one). Otherwise, it worked just fine with bulbs and manual controls. If problems arise, you may have grounding issues elsewhere in the car, which would not normally arise if the rear lights were not modded.

i did not know that... good to know... ill update the first post..

What kind of havoc are we talking about here? Especially on the climate control, as I would think most folks here have it!

Apparently, under unknown circumstances, the backlighting in the HVAC will change brightness with the turn signals. Nobody to date has taken the time to diagnose. I am unable to do it myself, as I have analog controls in all my cars.

cool mod, does it only do that when the blinker is on ? or when the brake is on ?

when ur lights are on... they are alternating...

when ur lights are off... they both blink...

when u brake, they both light up, but do not alternate

im confused i dont understand what its supposed to do?

go outside and turn ur blinkers on, then turn your lights on..

now what the video... the small unused 194 bulb now blinks with the turn/brakes without lights on, and with lights on, it alternates with the turn signal

and why is that cool?

who said anythign about cool? i just like that it utilizes that basically wasted 194 bulb... but thanks for the positive comment?

ooo i got it no im not knocking anything i was just wondering wtf its for ok i gotcha =]
