'18 camplite 16DBS tail light out

[nolichuckyjake]

Hello, joined in late '17---and haven't posted since.

I have a tail light out on my trailer. All functions.  It's a complex-looking module, #22028-093-12V V1.0.   Is it likely the tail light that's failed, or possibly another source of failure?   Am looking for a replacement, maybe two--but don't want to replace it if the problem is elsewhere.   btw, the right tail light is working.

Appreciate any help on this.  This is actually the first issue I've had with the trailer in 14,300 miles since new.

Thanks,

Hah.  I did post earlier on.  Had forgotten.

My bet is on a corroded connector, either in or near the light. I've had a problem with water getting in and causing corrosion, plus LL used the clamp type connectors everywhere and those can fail. I'd pull the light and see if there is any corrosion in connectors.

Thanks.  Will do that.   I've already ordered a pair of new light assemblies.  Cheap.  $16.50 ea.  If I don't need it I'll have them in reserve.
