In some of my lights I have replaced the 1076 (which you can get from other places besides RV dealers) with 1004. This has the same base, but draws only 1 amp instead of 1.8 amps. It's not as bright, but a lot less heat.
You can get LEDs with the same base, but you will have to choose between two or three colors (warm, really warm, or cool). You must be careful to get LEDs that are made for auto use where the voltage can go to almost 15 volts. Many cheaper LEDs will soon burn out if they see more than 12V, which makes them an expensive purchase.
My recommended source is
http://www.superbrightleds.com/, where a number of other MOCers have had good success. Several have bought LEDs at Quartzsite, only to go to Super Bright when the dark leaked out.
Check with Dave Anderson or Robbie Simons for the latest update on LEDs.
