try these Ming's 1156/1141 Green Long Life 330 Lumens LED Bulb - Replacement Bulbs - Lighting - Electrical
I have been a long time advocate of autolumination fixtures, but I had an opportunity to try the ones in the link above for.. well, free. I was so impressed with them that I am converting my entire trailer over to them. The set I have has been used daily for near a month on an old school convertor and I have seen none of the sensitivity issues common in unregulated LED fixtures.
I have only used them for one nite on battery
only during a power outage, so I can't accurately attest to the current draw dent (Or lack of) In theory, it should be around .3 amps each (.27 to be exact)
'Round here, I can get them for 24 bones a PAIR.
