CMHSL LED install on my ZR-1 - ZR-1 Net Registry Forums

GOLDCYLON · 01-03-2010

Well I installed the LEDs for the Center Mounted High Safety Lamp or (CMHSL) on my ride this is a 15 Mins install tops. These are avaialable from CorvetteHID.com Tools you will need.

1. Soft towel
2. Flat Blade Screw Driver
3. Philp Blade Screw Driver
4. Torx Head screw driver.

First. locate the Two Torx Head screws on the underside top portion of your rear hatch glass. Remove these two torx head screws. A screw driver with a Torx head attachment driver fitting is all you will need you do not need a rachet wrench.

Second. Place the soft towel on the rear portion of your targa roof so you can now flip the CMHSL housing over upside down onto the towel. (Dont want to scratch or top now do we?)This can be done easily eventhough the wires are attached. The flat black plastic base may stick a bit to the housing but it will come off to allow you to do this.

Third. Using your Phillp screw driver remove the two screws that secure the Red Lens to the CMHSL housing. You will now need to remove the Lens from the housing to expose the 4 Bayonet bulbs in the reflector housing. Mine took a little while to come loose due to a sticky black weatherstripping gasket that mates with the housing and the lens. Pry up the rear and sides of the lens and it will break free. Do not pry up the front of the lens as if it was to crack here you wont be happy. Take your time it will all come up from the hosuing. Do this part slowly. DOnt be lazy pry one side then walk around the car to get the other side.

Fourth. Pull the old bulbs straight out of the silver reflective housings and install the new LEDs. The LEDs once installed need to be bent over to one side (see picture below from the install instuctions provide by the vendor). This is so as much as the visable LEDs surface is exposed as possible. I was surprised to find out these were red LEDs Vs White.

Fifth. Test your install. With the CMHSL housing still upsidedown on the roof open your door and put your foot down to check your work. If its good to go just reverse the install procedure and your on your way. GC

Look for the two TORX screws here. Between the Hatch glass retention bolts

Old bulb on the left VS. New LEDs on the right. Each circle represent one LED or six red LEDS per replacement bulb

See how the new LEDS have to be bent to the left or right? The goal is to get the six circles facing to the rear.
