I'm in the process of refitting new clearance lights on the Sunrader. Truth be told I have one installed, but it is about 106F outside right now so I'm using that as an excuse to stay in today.
A couple of questions have come up about the replacement. It is really fairly simple, but time consuming. I chose the M8 series from SuperBrightLEDs. I've used their fixtures in my stop/turn/reverse replacement project and their replacement LED bulbs on the interior. The M8 sealed units are wider than the original fixtures, but they're brighter, simple to install, and should last a very long time.
