I have never seen them in action. Does the cable release a catch that allows them to pop open? Do they open slowly with the nitrogen piston or is it like a snap open? How do they get back down? Do you have to push them back down by hand? Or does the cable pull them back down?

I've not seen them in action but yes, pull cable to release the catch and the hydraulics pop them open. (not sure how fast/hard). You have to close them by hand.
Here's a great place to learn all about it: http://www.pbase.com/9146gt/gt_mechanical_headlight_raisers |

Properly adjusted, you pull a release handle on the dash and they pop up. Your headlight switch only turns on and off the light. There are pictures in my project thread somewhere. I'll see if I can find them...

I like this idea...here may be a way to make the lights pop open half way and put some low profile led lights.

Someone also had a push/pull system in place at one point so that you did not have to get out of the car to lower the headlights.

Thanks for the info guys. I wasn't sure if you had to push them down by hand. The kits seem pretty nice and well done. I know it only saves a little weight but its just one less electrical thing to go wrong and it has a cool factor since I love all things mechanical.

although the weight savings may seem trivial it was one of many parts that collectively reduced the weight of the race cars. The added bonus of the headlight motor delete is that they lay outside of the wheel base at the very front of the car.

McMark said about #10# So 13# is in the ballpark. Especially if they pared away the unneeded wiring.

I read somewhere that the old formula was the removing 10 pounds was like adding 1HP.
But I've also read that painting ones car yellow will make it go faster, and that stickers add 5HP. Still, removing 10 pounds should make a difference in your Power/Weight ratio. Those motors are heavy. Zach |

Kits are kind of expensive but something I may consider when the time comes.
