I bought mine from Amazon
Here are the ones I bought for my camper"2013 Gulfstream Vista RSD"
2pcs 42-SMD T15 12V LED Replacement Light Bulbs + STICKER 921 912 906 - White
and
GRV T10 921 194 24-3528 SMD LED Bulb lamp Super Bright Cool White DC 12V Pack of 10
With these it sure saves battery power. Check with local RV dealer on the type for your camper they should be the same
Hope this helped
Happy Camping
