Installing LED Side Markers...

It is super easy, I haven’t damaged anything using this method. Do the fronts first. If there is a screw it will be in the back. You will know if they really don’t want to pop-out.

Not sure if you have a jack or ramp, but you can also access these from under the car without removing the liners.

Wow thank you much! That definitely should work for me.

I've been looking at how to do this myself since I have the LMR Sidemarkers (with startup) as well as Heritage-X. This has given me some insight into the easy peasy.

Mine's a 2026 model GT Premium 401A -- built in February 2026.

I installed the FORM corner marker lights earlier this summer, and it went exactly like the manufacturer's instructional video. No screws.

A very worthwhile upgrade -- glad I did them.

Wait till you do the Reverse/Brake and Reflector lights from Form Lighting

My 2 cents: I tried to install both. Couldn't get the reverse/brake light to work and it was a bigger project. I returned it.

The rear reflectors are easy, and if you do them at the same time as the side reflectors, even easier.

What issue did you have? I can only make the connection if i remove the outer shell from the light harness.

What was your issue with the reverse light? I called and DD sent a new light but I still have the same issue as above.

My 10mm bolt was covered in undercoating. Took me about a 1/2 hour for each one
