I haven't seen rebuilt units available and have a defective one in front of me. I've been aiming to reman it myself, but the key integrated circuits are so old, I can't even ID them in order to find a suitable replacement.
If you search the web, you can find pictures of the board. Similar boards were used in Firebirds (many years), Corvettes, Fieros, Lotus Esprits, and more. All of the components are basic, except for two MOSFET chips (one for each side) which sometimes burn up. (The solder crack issues are unavoidable, in my opinion, and related to how the harness connects to the board.)
This module is easily accessed in the engine compartment near the driver's side headlight.
I just received the LMC High & Low Beam Housings. I also bought Phillips 9011 & 9012 bulbs which don't fit.
My question is: Should I use a dremel to trim the tabs on the bulbs, or enlarge the openings on the housings?
Thanks,
John
How don't they fit? If they don't turn twist/lock into the LMC housing, just a minor trim to a tab on the bulb is needed. If they don't fit on the car, that's because the right-angle bulb is hitting the metal bucket on the car and you need to cut a notch in the bucket.

Thank You! Thank You! Thank You! You are the best! You could have simply said "Modify the bulbs". But instead, you provided a beautiful, clear drawing which shows exactly how to modify the bulbs, and modify the stock buckets. I love this forum!
Happy Thanksgiving and Merry Christmas to all y'all.

So, I turn my headlight switch on,the motors turn and the headlights pop up. Non of the headlights turn on though, And the fogs only turn on for a second when I try them. When I try to turn on the fogs individually I can hear the rely flick as they turn off for the split second that they turn on...Bought a new relay....Same problem for those. Sometimes one of my brights will turn on. So this tells me with the motors running the switch isn't the issue, I also completely replaced the stock male/female 5 pin connector socket, and I have good continuity all wires are correct . All my fuses are good. Intermittently the fogs will stay on. But the regular headlamps wont turn on at all....Any suggestions to my messed or ordeal?

What was your problem before you started the work on the headlights? Are you using stock headlights?
My first guess would be crossed wires or corrosion. If your parking lights, DRL's, and marker lights are working normally, I would agree that your switch isn't the issue.
Checking continuity probably won't tell much. I would unplug the 5 pin connectors and check the bulb ground and bulb voltages (low beam and high beam) Make sure you are getting good voltage to the correct wires and that they are in the correct positions in the connector body. The motor wires are right next to each other and the 3 lighting wires are all together on the other end of the plug. If one wire is out of place on just one of the plugs, it can short circuit all of the bulbs.
Yea, Ive checked everything, I'm starting to think its the headlight control module. I dunno if other people have had problems with theirs before, but this is getting fustrating, I check each bulb individualy hooked straight to the battery and they turn on, the plugs are brand new, freshly soldered and heat shrinked....FML

Yes, frustrating indeed. The module shouldn't affect the bulbs lighting.
You can also have grounding problems that do these things. You might start by looking for voltage at the light sockets and see what you get. If you have no voltage with any combination of socket wires, then you need to probe your new plugs at the motors.
Are your marker, parking, and DRL's working properly?
Then the problem is most likely isolated to the wiring in your front bumper between that motor connector and the bulbs. It should be straight-forward to trace.
How don't they fit? If they don't turn twist/lock into the LMC housing, just a minor trim to a tab on the bulb is needed. If they don't fit on the car, that's because the right-angle bulb is hitting the metal bucket on the car and you need to cut a notch in the bucket.
I finally did the Headlight Mod. This mod seemed like a pretty straight forward operation, but I don't think any mod I've done has ever gone as planned. Of course I couldn't just go with the LMC supplied 9005/9006 bulbs. NOOOOO, I had to go with the 9011/9012 Upgrade. So I modified the buckets like the above photo, but I ended up having to open it up more on the right side; no big deal. Of course when I went to install the buckets, I dropped one of the bucket springs down into the neverland. I finally found it by using a flashlight, a mirror, and a magnet. I got the 9011/9012 bulbs trimmed with my Dremel per the drawing, and that actually went well. When I went to install the new bulbs into the housing, I realized that I had to cut away some of the aluminum housing behind the steel buckets. Got all that done and then took a look at the stock bulb contacts and they were not pretty at all. Since I am after maximum light output, I cut off the stock connectors and then crimped and soldered the wires. BTW, I saw that the stock wiring is 16 ga. and the LMC supplied connectors are 18 ga. Finally, I got the new lights installed and they look super bright! Now I have to go for a ride at night and get the headlights aimed properly.
Thanks to all the forum members who went before me and made this mod possible.

Area to remove from the aluminum housings behind the steel buckets.
but might be a tad more easy if you take the assembly out.....
I did more cutting than that on mine to fit the projectors I have and I didn't remove the bracket/frame either. They are cast aluminum. Easy to cut. For the larger projectors I have, I had to cut off those bumps around the hole and make the hole larger (I think i had to cut a slot similar to the pic above - my car is in storage and I can't find pics of what I cut). You can cut with a dremel or small hacksaw like above. If cutting with a hacksaw, make several cuts leaving 1/8 tabs, break off the tabs, and file down the jagged cut.

Ok, MEGA problem
