I finally decided to install these lights on the Miata. Now to start, these are your typical cheap 55 W bulb lights. The reason I like these it's because they are cheap so they won't light up the road a whole lot, but I have found them to be helpful with the small cars. They just let people see me a little better. The other reason cheap is fine is that when my other car got hit, the lights were the first to go and since they were cheap, I knew I didn't lose much there. Not that better ones are bad, but I just want a little extra lighting at night. From using the other ones I had on the other car I found them to help people see me more than when I only had the two regular lights. The cars are old too so the lights are not the brightest, but when you add two more, it sure made a noticeable difference. People would actually wait a bit more than just moving right into my lane. So do I recommend them if you can get them. Do you need to have the most expensive, no. In fact the set I got this time didn't even have any wires or connectors, just the lights and brackets. Well only the power wire had plugs but the wires are a bit short and very thin, so you also get what you pay. I already knew the car had some wiring in it which is the other reason I didn't care if they didn't came with any wiring. I just went for the smallest ones I thought would fit better in this car. I had not even looked under there until I started fitting them. It's a very tight space, but I got them fitted without much trouble. I'll explain that in the pictures as I will be posting those in a second. You can find this light set specs here...http://www.banggood.com/Universal-Car-H3-55W-Fog-Spot-Lights-Bulbs-Clear-Lens-Bracket-p-969455.html
I took that wire rubber cover off and also gave it a go around the edge here. This was open quite a bit. Things should stay pretty dry now. I like how I can rotate the lights about 180 degrees in the bracket. That came in handy when I mounted them since I was able to put the bracket behind the light. Making the installation ever more clean since you can't really see any bracket.
The left side. Here you can also see that the right side of the bracket is not mounted. I wanted to see how long of a bracket I needed before making any holes. It turned out better than I thought. I was thinking of using a sheet metal screw up top under the bumper, but it's not flat up there. It has a slight curve, but it turns out I just need a small right angle bracket I can screw to the plastic here. This stays in place with just the single screw, but having the bracket to hold the other side should keep it held there without any problem.
Here are the brackets I made out of that one piece. I found this one to be a bit on the brittle side. After bending it twice it would just break, but that was from the end I needed so it made bending and cutting them easier. One bend and I had my small bracket. I have two other and thicker door lock brackets if these ever break. So it's an easy piece to make.
-Small and just happen to work in the Miata
-No wiring which you may need in other cars. At least one for the positive wiring.
-The bulb is soldered in and crimped. I would prefer a socket so that I can change the bulb if it dies for whatever reason. Since you can't do this, you either have to get a replacement light or a whole new set. Not the best option. I didn't realize these didn't have a removable bulb. My other cheap set did and was easier in this respect.
-The wires where just a bit short and thin.
-No ring or other connectors included for the negative wire. It would be nice if they included any to make the install a bit easier.
-The separate wiring kits costs more than the set of lights. So you may want to find a set that includes everything. I know there are many others out there.
-Not completely sealed around the bulb and glass. At least the glass adhesive seems to be holding.
Update, March 8, 2016.
I finally got my second set of these lights. Banggood was pretty good about sending me a new replacement set since I had problems with my first set. Unfortunately I just got these in the mail yesterday and one of the lights came all broken up already. I don't know if it was like that from the get go or during shipping since the plastic is barely broken. Either way, I can't use it as you can see. I'll let them know but I wanted to add this on here in case you are looking into getting anything from far away like this. I guess they could have used a box with better packaging but instead it came in a plastic bag with a bit of foam around. The first set made it through, but this one didn't so that's something to think about. I didn't even think about this until now.
Update, January 19, 2018.
I want to update this so that others don't have to go through the problems I had with these. My bulbs burned up and I drove the car for a long time without the lights. I finally went ahead and ordered some bulbs on online and swapped them into the lights. They worked great, but one day when I was driving down the highway I decided to turn them off and back on to make sure they worked. That's when I found out that the switch was getting pretty hot, so I left them off until I could get some new parts to add to this set up.
I decided to add a power line from the rear of the battery to the front of the car since the only line I could find was the blue line up front which is also connected to the heater I think. I added the line so that I could add an inline circuit breaker near the batter and a small fuse block up front for a relay that I wanted to add to the lights so the switch wouldn't have any problems. So without getting into too much here I'll just add the pictures and write down the information here.
After checking things with my ohm's law calculator, I found that both my 55 watt lights would only take about 9 amps, so I went ahead and just used a 10 amp fuse because the smaller fuse is smaller than what I need. So far, it works.
While taking off the second one, the darn light fell off because the ground wire on this other side also broke and of course when it hit the ground it broke the lens. Not cool.
This helps seal them from the elements a bit more. If not water will get into them on the first wash or rain. Ask me how I know.
Here's a picture of the box once again.
