This is a genuine, brand new courtesy light switch from MG Rover.
If the interior light in your Rover 400, Rover 45, or MG ZS isn't coming on when you open the door, this little switch is probably the culprit.
It's part number YUE100570, and it's an authentic MG Rover part, not some cheap knock-off.
This switch does double duty – it controls both the interior dome light and also talks to the alarm system.
It's a classic part, so if you're keeping an older Rover or MG on the road and in good shape, having the correct genuine parts matters.
Installation is straightforward – it just plugs into the wiring harness and screws into the door jamb.
Get your interior lights working properly again with this simple, genuine replacement part.
