Review on Anderson Marine E421R Oval Light by Freddy Hammonds

Perfect fit and very easy to install. Simply pry the old one out of the surrounding grommet with a small screwdriver and the block will pop out, unplug the three-pronged connector and plug into the new block (you can't go wrong, it only goes one way), then push it in. Back to the spout and done. Easy as pie and everyone should be able to do it. The device looks pretty solid, works and fits perfectly. I got this unit because it is sealed and not the original (421R) because I ride my ATV trailer in pretty wet places.
