The reversing light switch on a Renault laguna is in much the same as on many other cars. Basically it links to the gearbox or the gear lever, so that when the gear lever is at the reverse position it engages the switch. On the laguna it is on the gearbox near to the left hand end (from the drivers view). You must remove the left front wheel to see it more clearly and possibly the plastic under-engine plastic shield. The switch is normally open, and shorts out when you engage reverse, so you can test it with an ohm meter.
Check the brake light switch.
That's a first for me. Must have a short in the starter or the relay. I would change the starter relay first, and if the problem is still there, then change the starter. One of them has a short. Or, possible the ign. switch has a short and might give continual contact. Check that first.
you have to remove the starter to replace the relay and the relay cost almost as much as the whole starter so you are better off just replacing the whole starter.
check the wiring change the starter relay and clean ignition switch with electicial cleaner.
You have a starter/ignition switch mounted in the steering column and you have a starter solenoid switch that is mounted to the starter.
Starter solenoid?
Very simple just unbolt the old one and replace with a new switch.
solenid switch engages and disengages the bendix on the starter
