Was hoping to just replace the lens but a closer look at the plastic base showed it was brittle and cracked in several areas. I ended up replacing with an Amazon led version.
Opps, it's a 2003, not 2002. I bought it new in 2003 and the Lance brochure for that year shows the same long marker light. Would like to replace it with another "long" one but still can't find one approx. 12"-14" in length.
All of the campers in the brochure have three individual clearance lights in the center, so did my own 2002 Lance 915. The lights on your unit may not be the ones that came with the camper originally.
