i'm getting my trailer ready as i'll be pulling my boat out for the season soon. checking lights etc. i discovered that the left side bulb is burned out. the problem? it's a sealed unit, so i can't get at the bulb. so i have to order the whole lens assembly. that stinks. my trailer is in my driveway, so it's no big deal. but, what if i was at the ramp & both bulbs blew? i guess i'd be out of luck & have to tow with no lights. i know there sealed to keep water out, but there must be a better way. what do u guys think? just venting!
