Hi, Smacked the left-hand/passenger wing mirror off the gate post yesterday. The clear plastic 'lens' that covers the indicator lamp LEDs is smashed but the main housing of the mirror unit seems fine. Can anyone confirm whether or not the 'lens' is replaceable on its own or do I have to buy a whole mirror unit? I've an '03 W211 E-class. It's got the spring-loaded mirrors that do not manually fold or electrically fold. (If you're confused by that, see this thread.) Would appreciate the advice. Tx, Ken.
