Default Led headlight install




Bought one of each of the best rated Led headlights from Amazon. I think the left (passenger side ) one looks better. Both seem to have good light output. Both bulb products were about fifty bucks.
The stock headlight mounts were not compatible. I set aside the stock hardware and fabricated a bracket to hold the big square backed leds. The main market for 5-3/4 leds is for motorcycles. Led bulbs that fit the dished mounting surface of c3 corvette seem too expensive. Ill drive around for a week or so then order 3 more of the bulb that seems better.
making the brakets was more fun than expected. I enjoyed fabricating the small steel parts. The final product is nothing pretty but it does the job of holding the new lights and is not visible once the headlight covers go on.

Nice job working around the stock buckets.

I have a BMW headlight 'ring' that I'll cut up and do something similar.

Creative with the threaded rod!!

If you do the electric headlight conversion- I have a harness that'll open the lights then when you turn off the lights and leave on the parking lights on-they'll stay up and run the DRLs. Turn off- and they go down.

Can you take a picture of them shinning on the garage door or a wall, I'd like to see the light pattern they cast, thanks.

Nice looking headlights. If I ever drove it in the dark I'd look at doing the same thing.

It does BUT what happens when a rock or something hit one because the plastic headlamp protector is not there anymore?

Drove at night for the first time. The led head lights exceeded my expectations. They really work well to light the road. I also noticed a defined end to the light beam so they probably dont blind oncoming drivers.
Final step is to fix a broken part of the headlight braket assembly under the front bumper. The broken corner causes the headlight to vibrate when I drive over bumps.
Richard,
I did miata headlight motor conversion a few weeks ago. I wired in a relay so the motors get power at ignition on and open when side marker light goes on.

I've had my eye on the ones on your passenger side for a while. Those and the other Harley lights with the horizontal bar. Can wait to see them lit up all the way across.

Are you going to switch out the inboard lights as well and wire them up for the high beam? Just use the outboard for both high and low?

I think I will just do the outboard lights. They function as high and low beams. If I could find some cheap brackets I would do the inboard lights too.

Thanks for the picture shining on the door, I wanted to see how the pattern cut off and it looks good. I definitely don't want to blind oncoming drivers! Almost looks like they could be a bit higher; do you have a way to adjust the aim with the mounts you made?

That beam pattern looks pretty good but the right beam seems to have a "hot" spot. The level to me looks good especially with bright white lights. SUV's and pick ups with yellowish halogens are blinding since the lights should be set much lower than the Feds are allowing..they blind oncoming traffic using cheap plastic lenses, not to mention HID's and LEDs....

yes I agree they need a bit of aiming. The little pads on the end of the threaded legs can screw up and down the threaded legs (after mounting screws are removed ) to allow adjustment. The threaded legs can extend into the gap between the orginal cast aluminum mounting bosses allowing lots of adjustability in or out. The brackets would be much better if you could adjust from the front by simply turning screws. The original bucket adjusters snapped on me when I first tried to adjust without dissassembly so the stock setup also seemd to lack easy adjust feature. I also found that the headlight mechanism
was adjusted to raise most of the way then stop making it impossible to remove the painted headlight surround trim piece. I fixed the raise lower travel
issue with the miata motor install. So before the rebuild I had both lights mostly but not all the way open and one broken adjuster making the drivers light point straight at the ground. Also dirty connectors made the lights extra yellow and dim.
I had a few Uber drivers almost run into my black vette at night I presume because the lights didnt catch their attention.

Good info, thanks. If I understand the issue with the lamps you are using it is that they are too deep to fit in the standard metal buckets so you made your own mounts. You mentioned that lamps you found that do fit in the stock housing seemed expensive, what lamps were they? I ask because the details given in the ads are lacking to say the least.

The lamps that do fit are from
dapperlights.com or similar light specialty websites. They are glass housings with led halos that can accept halogen or led bulbs in the center. Probably an excellent choice. I considered these but didnt like the price (almost $600 with led high and low beams) and I like the new led light assemblies better than bulbs in separate housings that seem more like a conversion. I was also concerned about spending extra to get a direct fit only to find I needed to cut up and modify the enclosures anyways.
