If you need to replace or would like brighter rear back up lights, I found the correct size for the rear bumper on my 2004 Patriot Thunder. An incredible difference lighting up the area behind the coach! An eBay search of 92MM X 150M lights will bring up a selection of lights.
Following are the lights I used.
