I finally got around to replacing the lights in my saddlebag and trunk lenses.

The saddlebag light lenses are aftermarket and have been on the bike since 2004. The lights were finally going bad and it was either replace the bulbs or retrofit with LED. LED was the best option. The lenses came apart easily since they were screwed together rather than glued together. The process went well and the LED's are nice and bright.

Made the trunk lights looks really bad, though. Now I had to replace them too and I was not looking forward to the hassle of taking those glued puppies apart. I read earlier in this post that those lights are really tough to get apart and it takes a lot of time and patience.

I also remember once upon a time reading that there was an easy way to open them up, so I tired it. Worked really well.

The method I used was to put the light assembly on folded aluminum foil in the oven. I could have used a cookie sheet but I was worried that the cookie sheet would hold heat better than the aluminum foil and mar the lens. Besides, the foil was handy and could be thrown out when finished.

I turned the oven on to 240 degrees. When the oven reached the selected temperature, the light assemblies were all warmed up and ready to open. A slight twist with a screwdriver and they open right up. Fifteen minutes tops.

I didn't clean off the glue. I left it so I could reseal it using the original material. When I had all the LED strips in place, I simply put the light assembly back together, warmed it with my heat gun around its perimeter and squeezed it shut.

Brilliant. I love it, and will use this method next time I have to do this type of job. Much easier to control the localized amount of heat as well, instead of trying to manage it with a heat gun.

Used the same method for my lenses too, worked brilliantly. Tried a spare pair i had on the BBQ............. That ended in tears, plastic tears :roll: :lol:

Going to replace all the lighting on the back with LED, but planning to do it a bit different as Wingadmin, with 15 round 40mm halos for the running lights and 8 fish eye lensed lights for the brakes.
They fit together and are much more noticeable when brakes applied. Will take pictures this winter and report back
