Currently Lasalle Bristol does not offer a replacement lens for the Gustafson 12V RV LED Puck Light GSL9538 # 277-000344. You would need to get the entire light or switch to a different light like the Command Electronics # 328-K-58L34P9 which offers a Replacement Lens # CE54FR. Do note the Command Electronics is only 4-1/4" diameter versus 4-1/2" on your Gustafson. view full answer...
