LED/HID Headlight conversion yet? (H4)

I have the Hella H4 conversion headlights on my CJ, and they put out lots of light, but I was wondering if there were any practical conversions to put HID or even LED units (replacements for the H4 bulbs?) into the jeep. LEDs in particular would (theoretically) put out good light while saving a lot of power.

I'm sure the HID upgrade is possible, but last time I looked at them they cost too much to be worth doing.

Anybody got any intel on this?

I have HID's in my Dakota and the extra light they provide is a bonus as I drive a remote highway late at night when I go back and forth to work. They put out more light than a halogen bulb but they should only be used with a projector lens designed for HID's.

I had to retrofit projector lenses into a new set of aftermarket headlight housings so that I wouldn't be one of those doosh's I hate....you know, the guy rocking purple HID's in his '95 cavalier with a plywood wing that blinds all the oncoming traffic regardless of hi or low beams.

Lots of people think using HID's gives them more light because they are that much better. In most cases that seems true because those people put HID bulbs in an OEM housing with a reflector designed for a halogen bulb. The light scatters way more and the cut off line becomes almost non existent. They have more light output but it's at the expense of the safety of drivers coming towards them.

My HID's do put out more light but it's not as drastic of an improvement as I expected. And remember, the lower the number of the bulb the more "useable" light you get. ie. purple 12,000K bulbs suck in the dark when compared to "yellow" 3500K bulbs.

I can't speak for LED's as I haven't researched them at all but I would think they would need a specific reflector/projector as well.

I went with the LEDs, I have never been so pleased. There is no more of the power sucking when you turn on your lights, there are bright as Heck at night durable and they will probably last forever. THEY ARE EXPENSIVE I saw what they were asking for them @ 4Wheel Parts. I am lucky because the Army LMTV lights are 12V, not 24V, and it was an easy mod. Found a good pair. This is just one less thing that I have to screw with, no changing over wires, and so much less pull on the Alt. Plus I think it kind of adds a nice touch to an ole CJ.
