I used Alla's S-HCR's. Unfortunately when I checked recently they only offer the exact bulbs as 3000K/yellow in the Insight's size. They seem to have come out with newer to replace them. I think they're the same ones that Rainsux or another IC member uses. I suspect my power draw may be slightly higher than yours because they do have fans. If I were to do it again I would probably get passively cooled ones just for reliability and ease of installation. The fans haven't malfunctioned yet.

I don't modify the housing, so if a ballast goes, I just throw a halogen in, which I keep as a spare in the glove box.

So far I've found HIDs to work well in projector housings, and LEDs to work well in reflector housings.

My LEDs were very efficient... I'll have to dig it up again, but something like 10w each.
HIDs would be nice, but I'm skeptical about using them without projectors, and I'd rather have the power savings and simplicity of the LEDs. I need to measure the power draw of mine.

Are they the same LEDs as are on the Fit? How does the light output compare between the two?

I haven't driven my car enough at night yet to have a good comparison, and the Fit's lights are fogged over right now. However, I do have the impression the Fit headlights are better, all else being equal.

Made 47.5mpg on my way to work this morning, low 20's and with the roads being practically soup.

I think the grille block is way more important with this engine than the old one. Without it, it won't get up to temperature in this weather even without running the heater. I could let it idle for 5 minutes and the coolant would end up warmer than if I drove it for 30. I know the thermostat works, so my suspicion is that it's simply air passing over the engine block itself. Too little load, too much block surface area. With a 95% grille block in place it warms up quickly.

My experience is that LEDs have a terrible light pattern in projectors, but good pattern in reflectors. I was going to replace the HID kit in my Prius projectors, but I couldn't get a decent pattern from them.

Instead I put the LEDs in my reflector housing on my motorcycle.

Turns out I posted a while back that I measured them at 15 watts each. The product description says 25 watts each, but I wasn't able to replicate that even after half an hour of them heating up. Voltage doesn't matter either. They consume roughly the same amount regardless of voltage.

One thing I don't like about LEDs is that I cannot find any that have a color temperature below 6k. That's more blue than I care for, and would prefer something closer to 4k.

Guy on Spyderchat is a big headlight stickler, I think he says JDM ASTARs are good since they mimick a filament sized light source.

I used to run some really weak Ebay LEDs, and I will admit seeing at night was actually pretty difficult. Definitely get the better stuff.
