"billet led dome" works on ebay, look for the radius mount type. I used this for the front:
and two of these for the rear:
The back is controlled by the rear passengers via a switch on the back of a tuffy console and the front is controlled by a dash mounted switch. Or I should say will be LOL still getting it all together. The leds mount in some brackets welded to the cage, kind of dual purpose gussets and led holders.
The leds are fairly bright compared to a regular dome light and vibration a water proof.
