Recently the 3rd brake light bulbs on my 94 LS400 burned out, and I got the warning light on my dash. I replaced both of the bulbs for the brake light and noticed that the light was still on my dash. I noticed that one of the bulbs had a loose connection as it would cut on when I wiggled it but would turn off pretty easily. Now, because I am a genius I thought it was a good idea to wrap the base of the bulb in aluminum foil to fix the loose contact. Neither bulbs work on my third brake light now, so I was curious if somebody would know if the 3rd brake light shares a fuse or has it's own fuse with anything else. I would much rather replace a fuse than have to figure out how to go wire chasing to fix this and I really want to get this light off of my dash.

Thanks!

A real genius would pay attentions on the galvanic corrosion issues and do not use materials like aluminium.

Will have to pull the high mount and inspect the housing and the connections. As you mentioned, check the fuses to verify. When these bayonet type bases get loose, a thin flat screwdriver to bend the contacts is what I've done. Of course make sure that the battery is disconnected to not short or shock yourself when poking into these connectors.

At least its a common part at the pull it yourself junkyards.

There is only 1 fuse for 6 tail brake light bulbs and 2 centre brake light bulbs. Those 8 bulbs are getting power from a single fuse.

If your tail brake lights are OK and the centre(high mount) brake lights are not OK, you probably damaged the tail light failure sensor unit or the wiring/connector. See inside of the unit in the trunk. You would find a damaged current sensing resister or it's related soldering points. This is a common problem when someone tries to install LED lights and accidentally causes a short circuit. There goes a big current and it damages the current sensing line before the fuse opens since the fuse is too big to open by the instant current spike.

I must be missing something but HOW do you get access to the bulb in the High Mount Brake light? I've pulled the trunk lining and I can't see where or how to access the bulb? Btw the manual is of no help for the '98 LS. Any advice? Tia.

Yamae I ask you the same question, how do you gain access to the rear high mount brake bulb? Is it from the inside of the vehicle? I can't see the bulb when I pull away the trunk lining, how in the heck do you get to it. Thanks.

For all LS 400s, you must remove the rear bezel for the middle brake lamps. The 1990-1994 1st gen models have a bezel that is combined with the subwoofer cover. 1995-2000 models have a bezel dedicated to the middle brake lights.

Here is how to remove it. There are clips holding it in, and you remove it from the rear deck inside the interior. No need for any major disassembly:

I just did this for my 2000 LS400 yesterday, I believe it is the same as yours, the housing is separate from the sub, I slid a pocket knife under the housing and pulled it towards me and up, start with one side, then work on the other, hope that helps.

Thanks a bunch, the link was a BIG help, much appreciated.

Yep, it does the trick, thanks so much.
