Ya, the ones I purchased I could not find many reviews on. But I looked up the specs on the LED's that are used in these units and I think they will be bright. They are supposed to use 20watts per bulb as opposed to the 100watt per bulb halogen's I currently have. Their are some on ebay that are older versions, and I found a couple reviews of them and they were all good reviews. Here are the ones that have been around a bit longer and you can find some reviews on mud about them:
CREE MTG 72W 6400LM 6500K White Hi Lo Kit H4 Car LED Headlight Daytime Bulb Lamp
I think the people on mud that use them however get them through a mud vendor called lifetime led or something like that. But they are cheaper on ebay, just with less of a warranty. You can also get HID bulb retrofit kits for the h4 housings which are very bright as well and they draw between 30 to 50watts per bulb depending on version you buy. DDM tuning has inexpensive kits if you want to go the HID route and their bulbs have lifetime warranty.
Keep in mind that I have been looking into the budget route for me personally as I have a lot of other stuff to spend money on my 40 at the moment. Some people may decide to go high end with lighting options, in which case I haven't done any research on that route.
I really like the idea of reducing my current draw because my BJ40 originally came off the production line with sealed-beams of just 50W/40W rating and I believe my headlight wiring and switches were never designed to handle much more current than that (so I suspect my present 60/55 H4 bulbs, although not considered bright by many here, still somewhat tax the current-carrying-capacity of my wiring and switches).
And I love the simplicity of my old BJ40 so I'm averse to installing extra relays (and to installing HID headlights that have to receive extra voltage just to fire-up).
I'm guessing I could still run my "rubber dust boots" when using your new LED bulbs? (I wouldn't be keen on going without them so that's a big plus.)
And I'm also guessing the braided metal hanging off the back of each bulb is its heat-sink? (I think I'm tight on space behind at least one of my headlights so this flexible dangling design looks better than the solid heat-sinks I see behind other LED bulbs.)
Shame the designers couldn't incorporate the 3-pin terminals solidly into the back of the bulbs somehow though.. (That would make the installation look a lot neater in my opinion ... but I acknowledge it would also be tricky to achieve without encroaching too much into the space behind.)
Anyway .. Thanks for getting me thinking on this... I'm tempted to follow your lead ... but I'll hold off ... at least for now.
