There are a few threads about the Toyota/Koito H4 kit. Posted my impressions in those, but for the sake of future searches, I'll post it here as well. There are plenty of pattern pics out there so I'll save the band width.
Thanks to @Longwhitejeep for posting what I think is the first post on these lights.
I purchased for $45.58 out the door (no shipping needed).
Picked them up yesterday and installed them them last evening. My very early impressions...
The Good:
- As others note, the kit is a steal for the price. Complete with a bag of way-to-many zip ties.
- Build quality is great. Glass is crystal clear. I like the flat lens.
- Beam pattern is what I remember from the IPF housings I had. No dead spots like the LEDs had. Sharp upper cutoff with a clean rise for the right-side ditch illumination. The LEDs were spotty with bright spots where there shouldn't be and plenty of dead spots. I did a rough alignment and coverage with this kit is a nice smooth, even wash of light where it should be and nothing where it shouldn't. I need to adjust them both up a bit..
- Install was plug-n-play.. bulbs were already installed. Pop out the old and in with the new. It's a one-banana job.
- Stock bulbs ran warm enough to remedy my concerns of ice/snow buildup on the cooler running LEDs. That's a real problem here in the NE. Problem solved. That said, the polycarbonate lens of the LEDs were less susceptible to cracking and chipping than the glass. I've got a set of Lamin-X clear protection film so no worries about chipping
- Though I like the LED technology the look of the H4 lenses is more period correct for a 20+ year old vehicle
The Bad:
- The bulbs that come with it are woefully dim compared the TruckLite knockoffs. I have a set of Hella 100/80s in transit from Q-Tec which should be measurably brighter so this is a manageable issue
- Same goes for the color. If I hadn't turned them on with only one installed alongside the LEDs it might not have been so painfully obvious, but the color is almost yellow. After driving with them for a bit the color difference began to wear off and I know there are tons of bright white H4 bulb options, but I fear the ones I bought from Q-Tec might not be the solution
- I did a rough alignment but still have one spot where the overlap is leaving it dim. The side-to-side adjusters in my buckets might be shot, so once I fix that I should be good.
- The end fittings on the harness are definitely too small to fit over the battery terminals. An easy fix.
The Ugly:
- The high beams... ugh. Hard to tell just how bad they are with less than an hour of seat time and the stock bulbs, but the high beam is not great. It begs for a set of auxiliary lights, which I haven't installed yet.
For less than $50 plus a a few pennies of gas and tire wear to pick them up, these are a bargain worth spending on. The harness alone, high quality and complete, is worth nearly that much. Since mods are never really DONE, I'll have some fun experimenting with bulbs once the harness is installed. No solution for the high beams, though I use them so infrequently it isn't a big deal for me.
After a second round of alignment, any dead spots I was seeing are all but gone. Plan is put the harness in this weekend and then the brighter
