Brake light problem
My problem is that my tail lights will not go out!!! I have checked the fuses and replaced the brake pedal sensor since I thought it was the brake lights stuck in the on position. Turns out that the brake lights seem to be working fine when I am using them but the tail lights will not go off which drains down the battery. It sometimes appears they are off but then they will come on. For instances I thought I had found the fuse controlling them and pulled it. They were off and I was relieved but a while later they were back on. Now I have to disconnect the battery when I park to prevent draining it.



Any assistance would be appreciated
Thanks
Lexus has different filament for brake and tail light. That you already found out.
IS your light set for auto? Try turning it to OFF and see if the tail light behaves differently.
When you see the tail light on (after shutting down the RX) do 2 rapid (in succession lock button press on your remote key) and see if the tail light shuts off.
Do you have trailer connection? Who installed it? Is it possible for you to disconnect it?
Any idea what started this odd behavior?

Re: my first post
The tail lights started doing this randomly as far as I know. I have changed the brake pedal switch without result. The tail lights will not turn out intermittently meaning that sometimes they are off when I check after removing the key from the ignition and sometimes they are on. They also will appear to be off and then come on later so you are never safe to assume they are going to stay off.
The trailer hitch was on this vehicle when I purchased it and my reading in these forum threads seem to suggest that this was a standard on this model year?
I have purchased new bulbs for all the rear lights but then read that the bulbs often lead to more problems so I have not installed them yet.
One clue that was not obvious to me before is that there is an intermittent clicking sound in the steering column or nearby dash area while driving. May happen and may not happen at any given time. It leads me to believe that there may be an issue with the light control arm on the column.
Any thoughs?
Thanks for your ssistance to date and looking forward to hearing from anyone who may have knowledga, ideas for investigation and suggestions.
There is a brake switch, physically connected to the brake pedal and engages based on travel.
My instinct tells me that switch is sticky and that makes the clicking sound. You have to get in the foot-well and try disconnecting it. Do not drive around as you will be driving without the brake tail lights.
Disconnect it and if the brake lights stay off, then you have isolated the problem. Jiggling the switch can also reproduce your problem.
You can simply replace the switch and see if the problem clears out.

Brake pedal switch has been replaced and brake lights work fine whether tail lights are on or not. The brake lights have been ruled out as the issue based on this.
However, the tail lights continue to remain on or to return to the on state independent of control switch status.
The clicking is high up in the left of the steering wheel as you sit in the seat. It is not down where the brake pedal switch is located.
Additional info not to lead anyone down a false trail but just to add the missed symptom to the earlier post.
Thanks again to you and whoever else has any ideas or info that may help.
There may be more than 1 switch (I could be wrong) on the brake pedal.
Does your cruise control work? It should disengage with signal from the brake switch.[I am still on the brake switch]

Power is on, switch works, maybe it's a lamp Failure sensor that is bad? So where is this little bugger?
I have the rear trim panel down on the driver's side, by the spare tire well, but no little box or plug in. There is a plug in, but it's just a jumper, with no circuit inside. Strickly bars that jump from one side to the other.
Any help?
I did get sent a wiring diagram, which is super!
Thanks
