Hi all,
we just bought a very used but in reasonable shape RX400h for our youngest daughter. I’m going through and replacing and fixing stuff now. I found that one of the backup lights wasn’t functioning so I took out the socket to find it was melted and no bulb installed. I’ve been looking for replacement sockets and cannot find anything. Even RockAuto doesn’t carry them. Anyone have this issue and/or know where I might find them? It shows as a Koito with 11 on one of them and 1 on the other. The 11 has 178 printed on it and the 1 has XF.

thanks!

 

Outer socket harness is a separate piece but is the backup light on the outside or inside lamp? Probably inside.

Can you post a picture? There are about 20 different styles of 921 bulb socket.

 

What year 400H?

 

2008 going by this persons profile.

.......duh the part number for the inner socket is right there 90075-60063

 

I can’t post pics since I’m brand new, but it is shown in the diagram as 81555C.

 

Ok, I’ve got it now thanks to that link! It’s part 90075-60063 so now I can order a new one. Thank all!
