So for the last few weeks I've been having an issue where the parking light on the passenger side stays on, even after I've left the car for a few hours.

I'm not 100% sure what the light actually is, whether it's a general turning light, or a parking light, but in either case - it's one of the small circle lights at the base of the front bumper that turns on when you steer left / right. I only notice them when I'm parking, but it might do the same when going round tight corners as well?

Ordinarily it will turn on when you steer in the direction, then turn off when you straighten up. The driver's side does this fine, but the passenger side sticks on. Not always, I can see it turn on / off in the reflections on other cars and windows, but typically by the time I stop the car at my house it'll be stuck on.

I thought initially it happened if I went full lock left so have been trying to avoid doing that, but it seems to be happening more generally now.

To fix it occasionally works if I reverse full lock in either direction, or if I drive around the block, typically turning right. Invariably I find myself trying a number of arbitrary manoeuvres for 10 minutes each day until I get fed up and it either works or I leave it for an hour or so and come back to try again.

With regards to the various other lights, as far as I can tell sidelights, dipped beam, full beam and fog-lights all seem to be different lights and all work fine. Equally 'follow me home' lights do work, and will turn off after the relevant time, but leave this one solitary bulb shining away.

Short of just removing the bulb, I'd love to work out what it is.

Ah! Cornering lights makes a lot of sense. Now I know that's the name, it looks like I'm not the only one, although this seems to have been left unresolved.

I need to have made 5 posts to be allowed to post URLs it seems, so until then - it's on the FiatForum - thread name "STRANGE BEHAVIOR: Corner light doesn't turn off"

/punto-evo/311296-strange-behavior-corner-light-doesnt-turn-off.html

There's a link to a youtube video in there as well. It's not the best footage, but the video demonstrating the issue in that thread is the exact same problem.
 
There is a relay that turns the cornering lights on, this is separate from the usual engine bay fusebox where other relays live, they are also prone to rusting which could cause an internal short and leave the light on permanently, I have the oposite problem with mine the relay fell completely apart internally and the cornering light on that side wouldn’t work any more.
