Has anyone put a red pod light in the bumper, instead of doing a white reverse light, I was told that you can’t splice into the break lights though, any info would be appreciated
Baja Designs does not make a kit that lets you tap into the brake lights. You are correct in that you'll run into issues. Your truck will think you have a trailer hooked up if you tap into the brake lights. Thanks to that lovely BLIS system and trailer system, the circuitry is monitored by the computer in the truck. It'll sense extra resistance by tapping into the brake line and think it has a trailer hooked up.
What you could do however is tap into the circuit elsewhere and use a relay. This way your not giving the computer a load and the relays will handle the job of providing power to the lights.
GJ Motorsports kind of does this with their system. They use a module to turn the left and right S2 lights on, to act as blinkers, in their 3rd brake light kit. Same idea basically only you'd want to tp into the circuit elsewhere (up by the BCM cables is where i'd do it).
It's going to be more of a hassle then I think is worth it. I've never been a fan of additional brake lighting in the back of trucks. It's a bit much. Our trucks a pretty bright as it is with the factory brake lights. You'd just be taking away from that nice clean look back there with additional brake lighting.
