New H4 headlights just arrived_question

[SoCal911SC]

Just received my H4's today and was wondering if there's a seal or gasket I need to purchase separately or if these just mount in?

I've read some horror stories of units falling out from the single screw that holds them in and wondering how others have secured them from falling out. Thanks!

Yep, there is a gasket that sits between the headlamp assembly and the fender. Gasket will be seamed and flat on one side shaped on the other. Shaped side toward the fender. Seam at the bottom. You'll have to stretch the gasket on. Start at the top and work down stretching as you go. You don't won't too much pressure on the seam or the gasket will separate at the seam. Hook the lamp assembly at the top, compress gasket as you press in at bottom of lamp, then insert screw while there is no pressure on it. -J

Yes, you need the headlight rubber seal. See: Porsche 911 (1974-1989) - Lights and Lenses - Page 5

Good info. Do I stretch the gasket/seal onto the assembly or onto the fender?

Yes, seals (Pelican Parts) go between the Euro H4 headlights and the fenders. There is some skill involved to get the seals in the right place and secure them. Then there is the question on how to securely mount the H4's themselves. It should not be a big problem if the fenders are almost new and not bent in some way by repair jobs. And last, there should be relays (also Pelican Parts) installed with the H4 headlights to prevent heavy currents going through the headlight and dimmer switches.

Upgrading To H4 - What To Do With "City Light"?

After all those posts, I would not be too anxious about the safe mounting of Euro H4s. I have done it a year ago on my all original '79SC and it was not a big problem. I found out that the most important thing is to make sure that the M5 light mounting tab is bent sufficiently downwards. So much so that it is somewhat difficult to engage the Phillips screw driver. The screw driver should touch the bumper and still not engage straight with the mounting screw. Only then do you get enough downward pressure on the head lights to securely engage with the holding tab on top of the light buckets.

Good luck!!

You stretch it onto the fender. Using silicone grease helps to slide the H4 assembly on.

While the weather is still warm, so you can lay the gasket out in the sun to make it easier to work with!

Read post #19 regarding proper fitting gaskets. Also if your gasket does have a visible seam place it on the bottom, if it separates it will allow water out. I agree with light silicone type lube as well, it's actually good on all of the light lens gaskets.

Euro H4 conversion a costly lesson

Can anyone confirm if they are HANDED? my left one doesn't seem to line up good.
Can't see any difference in part numbers and most advertise as left or right so thinking not.

Thanks Brent

They are not HANDED. Left and right are the same.

[brentrussell]

Thanks Dennis for the confirmation.

I carefully bent the metal edge around the headlamp opening out just a little and added a lanyard just in case. I also ran ignition power to the running light inside the headlamp so when the key is on the running lights come on.
