I’ve done this a number of times.... and FAILED badly with my 2018 f150. In that truck, which has notoriously poor lamps, the plastic rear housing softens in the oven before the 5.5 linear feet of glue. Yes, that was a surprise, it didn’t go well.LED headlamps are the new norm and thus, are / will be repairable. Bake the light, remove the lens, change the LED, and seal it back up. Only those that can't DIY will pay the big bucks, same as it is now. High dollar headlights are nothing new. HIDs have been self leveling since their inception - ever price out one of those?
