I have a 2011 SHO and both headlight lenses are shattered. This is my wife’s daily driver so I need a plan. I can’t seem to find a drop in set of HIDs for less than 1000,000.00. How big of a problem is it to switch it to halogens? Those seem to be available.

I had no idea about that site. I ordered a new aftermarket set from eBay. I just need to figure out the wiring.
Does anyone know how that’s going to go?
Next concern is will the automatic high beams still work?

HID or halogen? There are aftermarket HID on eBay for @300 each.

Those all appear to be halogen and not a direct replacement.

HID

I have HID but I'm converting to halogen, I already have two new halogen lights. There's a four pin connector that connects to the housing for the headlight bulb. one is hot all the time even with the ignition off. on high beams there are 3 of the 4 hot, on low beams there are 2 of the 4 hot. My thoughts are there should be 3 wires for the headlight bulb. 1 Ground, 1 high beam, and 1 low beam. I think the low beam turns off when the high beam turns on, is that correct?

Ok, the headlight plug has two rows of pins. One row, I assume is for hids and the other maybe for halogen. So the plug on the car uses one to and my new headlights use the other row. I need to know what each pin on the halogen headlight needs to have going to it. From there I’ll try to repot the plug to make it work.

You will likely burn out your Smart Junction Box (SJB) if you try to power your halogen headlights off the factory HID wiring harness. The HID ballasts are driven off of FETs within the SJB, whereas the halogen system uses relays powered by 20A fuses in the Battery Junction Box for each headlight. The relays are driven by FETs in the SJB, so you may be able to get by with adding relays and manipulating some wiring. Are the new headlights you got projector beam? Because if so, they use shutters to switch between high and low beam rather than having a separate filament for each within the bulb.

On the HID headlights, there is a power wire for the ballast (pin 9, hot at all times via a 20A fuse), a low beam control for the ballast (pin 8 that is controlled by a FET), a ground for the ballast and shutter (pin 11), and power for the shutter (pin 10 from high beam relay in SJB). The wire colors are different for right and left, but the pin numbers are the same.

For the projector beam, there's power for the bulb (pin 3, fed via headlamp relay controlled by low beam FET and a powered via a 20A fuse), ground for the bulb (pin 2), ground for the high beam shutter (5), and power for the shutter (pin 4, hot on High Beam).

You are likely right. It's not a simple rewire. The wiring is completely different between the two types of light.

I bought LED for my ‘94. Unfortunately, the electronics didn’t like them. The bulbs worked, but the “lamp out” light would come on the dash. I ordered Capicitors to remedy. I still have them because the bulb retainers were so brittle that they began to break them. I still have them in a box for anyone who wants. I got the original bulb retainers to secure the original lights back. I would like to find OEM bulb reatainers used/new fine. But, I’ll get Capicitors again after I find bulb retainers. Still, if anyone wants this new set, they are free.

Thank you for the reply. I bought a couple bulb retainers that some company said fit. Not so. I will try these. Again, many thanks.
