Yes, as a matter of fact I do, BARJAN (Well that used to be the company name) Lamps can be found at many truck stops, all "Chrome Shops" .. Look for LED back up lights
Any of the surface mounts on the following link if it is still valiid (Is as for today 2/5/2014) Reverse Lamps | Truck Lights & Lamps | Truck/Trailer | Super Bright LEDs
Friend of mine got one designed for trucks, with the "Armored" housing at a local Super Store in MI (Meijer's) and till he pointed it out I did not know he'd switched to LED. IT was that good a match. You can fit two of them in the standard Thin-Light housing after you gut it of the lamps and Ballest, Use the very same switch, cut way down on current draw (These things SIP power) and get more light.
