I'm an idiot. I know the GM LED lights have internal flashers. Why? The replacement lights I used on my car are basically the same ones found on a lot of garbage trucks, service vehicles, etc... They have internal flashers and are programmable. All the GM T53 relay kit does is provides 12V power either "on" or "off" to the leads going to the lights. If I remember correctly it's switched using the same circuit as the trunk lighting.

It's a shame we don't have the pin-outs on the light boards themselves as I can see through the clear plastic that they are called "GM36BW r2.1" and "GM36RA r2.1". I'll bet dinner at Outback these suckers are programmable for light color and flash pattern, just that we don't know how to do it. The LED light units are listed on the backs as "GM Rebel LED Blue unit, GM 381-2, Kerr SJC19971-B" and "GM Rebel LED Red unit, GM 381-1, Kerr SJC19971-R". The lights themselves have five conductors coming out the rear, Purple, Gray, Green, Black, and White. Looks like based on what I left behind the green and black conductors are used to power the lights, white was cut off. Purple and Gray were shrink-wrapped by Kerr and not used. If anyone has contact(s) at Kerr maybe they'd be nice and send out the instruction sheet on the light heads.

One nice mod to do if you have these lights installed is to put a switch in to kill the flashing. I never did that with mine, if I wanted them off badly enough I pulled Fuse #16 in the left side trunk fuse block. But, I did get tired of the lights going off whenever I'd get groceries. In the parking lot of the store when I popped my trunk lid, the lights I used lit the area in proximity of my trunk up very well. :mrgreen: Kerr does list this as an option in the upfitting guide.

To go all amber, this is what I used in place of the GM stockers; https://www.eccowarninglights.com/product/3945a-sae-i-round-grommet-mount-amber-directional-led Many outlets sell these now including Granger, I'm seeing prices of between $30-50 a unit just on a quick Google search. I reversed the GM brackets and mounted the lights directly to them, so in effect I reused all GM components except the OEM Kerr light heads themselves. Dimension-wise they weren't any larger than the older incandescent 9C1 light kit and nothing hit when I closed the trunk, so it was win for me and looked completely OEM. And had a lot more (brighter) LED's than the Kerr units - 52 LED's total per light! Here's how it looked when done (yes I left this pic a little large to show detail);

Just some food for thought.

I'm going to try a white set. Don't need them to flash though. I'll probably remove the flasher unit.

It's not a flasher, it's a relay. Remove it, get no worky. Unless the flasher unit you're going to remove is built into your add-on lights.
