The fuse that looks after the taillights and the interior lights in my L-series (Loyale in US) keeps blowing. The fuse seat sparks up every time I try to put a fresh fuse in.

What do you think is the reason for this?

Thanks

There's a direct short in one of the circuits supplied by that fuse. You'll have to find out what all runs from that fuse and start tracing wires and disconnecting things to track down the short. It's probably something pinching a wire agains the body somewhere. Improperly installed trim and badly routed wireing can cause that.

I'll bet a dollar that the wires at the tail lights either pulled out of the socket and is grounding out, or the wire is worn down to the copper at the sill that the tail lights sit in.

 

Also double check the screws holding the dome light into the roof. The screws are the ground and the power wire runs directly above it so if you used too long of screws in it you may have ran a screw into the power wire
