Lexus RX450h..rear brake light not working

[Charlie1955]

Can someone help please. My right rear brake light does not come on. After looking in the handbook and in the light cluster I cannot find a bulb to replace. How can it be fixed. Help.!!!!!!

I think they are LED, hence no bulb to replace. I'd first look at the wiring to the light cluster to make sure it hasn't been tampered with (e.g. from someone trying to fit a towbar).

It could be my fault then. I replaced the rear light bulb  in the cluster and had trouble getting it back in. If I have damaged the wiring, who is the best place to fix it..Lexus or any garage dealing with electrics.

Any garage dealing with electrics would be fine. 

Check fuses as well I would have thought?

Thanks for that. I will check fuses tomorrow

I had this same problem on my 2012 RX450H. it happened after i changed my rear side light bulb and straight after changing my LED brake stopped working. It would have cost me around £500 to change the the rear light unit. Had to be a better way.

After checking power coming to to circuit being ok i was baffled. I checked online and found other people in the situation after change rear side light bulb. My mechanic finally found out what the problem was. When you change the rear side light bulb you can very easily snap a very fine and tiny wire connector that connects to to brake LED light circuit. It is very hard to find but a good car electrician will find it. My mechanic, who is a friend of mine, just re soldered the connector and, hey presto, my brake light was working. Whats more he did not charge me.

I was so relieved and happy.

Hope this inf helps others.

I have a 2010 RX 450H with only one brake light working. Everything else works including the tail light. I recently changed a bulb with some difficulty and have power to the taillight but NOT the brake light. IS it possible I destroyed or tweaked a wire feeding the brake side of the bulb? If so what is the fix?

Thank you.

It's possible I suppose but you need to do some diagnostic testing to confirm.

Using a multimeter, do you get 12V to the brake light contact of the bulb holder when someone presses the brake pedal?
