LED headlight upgrade?

No relays needed for the Truck Lite. They only pull , 1.80a (low beam), 3.60 amps (high beam).

Similar for the JW speaker headlights, the 8700 Evo 2's show a draw of 2.0a for low and 3.0a for high. The 8700J's are a little more, 2.7a on low and 4.0a on high. They have a "anti-flicker" module you can install (not required), but that's a filter not a power supply or relay.

That's actually one of the reasons I want to convert everything to LED. Not only are they brighter, but in most cases they draw less power too. Your basic Wagner H6024 pulls 2.7a on low and 4.7a on high beam, with approximate candle power at 27,000/35,000 (low/high). The JW speaker 8700's are 35,000/60,000.
