How do you remove a light fixture cover to change bulb? Baja 195 RB. The fixture is white, oblong with acswitch. On the long sides, there are 2 small slots on each side. Easy pushing with small flat blade does not help. Ideas? Had trailer for 6 months and mostly OK. 2 leaks that are repaired, changed mattress for quality and good sleep. Lots of small adds. Added sat. outlet on side of trailer, using the ref space. Pulls nice going uphill-7500 ft uphill! Using F150 and 5.4 V8.
