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.

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.
