Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

How hard is it to change the high mounted brake light? I'd like to change the red one for clear plastic with red LEDs.

POST 2Original post

Not difficult at all. Put the top in service position so the clamshell is out of the way to access the two screws that hold it down and unplug the harness. Reverse steps to install. Be aware that on some Boxsters the third light, tail lights and cruise control are all tied together in the fuse box. If you install LED tail lights along with an LED third light the current drops and the cruise control will not work unless you install a resistore at the third light.

POST 4Original post

Be very careful with the light more importantly the bits that hold the light on to the screws. Mine came off in the car and fell in the trunk behind the liner and 2 hours later I found them.

Where should the resistor be installed, can it be close to the harness plug for the 3rd brake light?

POST 6Original post

Be careful the resister gets hot. Attach it somewhere where heat isn't an issue.

Yes if there is room for it and heed emore93's advice.

POST 8Original post

I am new to this forum. And see this older post . The two rubber cylinders that hold the third lite in place fell into the lower space and I would appreciate any help in how to retrieve them. Could not find in the trunk after removing the felt backing. Only the computers, etc. Am I looking in the wrong place? Thanks, Bill

you will have to "fish" it thru the holes in the frame.

POST 11Original post

I installed mine without a resistor and the cruise works fine.

POST 13Original post

Thanks for the pic and info. I will try to fish...if not successful I will order a couple. No Porsche dealer in my little town! Bill 2002 Boxster S 1991 BMW 850i 1971 MGB GT And a couple of newer vehicles

POST 14Original post

It seems I can't find them. Is there a trick to finding those rubber cylinders. Thanks, Bill

POST 16Original post

I'm tired of hunting. I'm going to buy them. Thanks for the help guys. Bill

POST 17Original post

Just a tip for anybody who cares. I took tight grommets put them in the holes. with a drop of super glue, so they would not spin and after about a half hour, I drilled holes just big enough for the screws to go through and remounted the third light.
