Suburbanator

I just picked up my new Suburban and I am searching for flashing LED brake light bulbs. I have come to understand the technical issues with these when installed on late model vehicles. I recently tried installing them on my 2013 ZL1 and ended up returning them, rather than hack the harness to install the needed resistors.

Everyone calls these bulbs, or harness adapters by different names (flashing, strobe, blinking, rapid fire...) but basically, that’s what I am looking to do with the main brake lights. I have already ordered a module to make the third brake light flash. I did the same on my ZL1 and was pleased with the result.

If if anyone has done this, or knows who sells the bulbs, or the harness, I would love to hear your suggestions.
