If the lens is gone or leaking, it could allow water into the trailer. If you remove the base, you might find a make and number you can look up to buy a replacement. If it's one of the group of 3 ICC lights, it might look better to replace all 3 so they match. (if you care) If it's on the side, being close to the original would be enough except for the real anal.
Your torsion bars could be tired or even broken. Some torsion bars can be adjusted by rotating the bar's base in it's mount. Check to see if your's can be adjusted.
