Trailer wiring

[Ace]

After doing more research, I found that the cheap convertors found at most auto posts stores and Walmart are only rated at 2.1 amps. Probably good enough got a small open trailer or boat trailer but definitely not good enough for an enclosed trailer with added marker lights and fender lights.
I ordered a hd valley converter today. Its rated at 10 Amps per circuit and there are four circuits. I think that might work ok.
To add I also ordered matching led lights four the rear of the trailer and then was mentioning that two of the 17 I bought in 08 were always flickering. They gave me the direct number to Bargman. After calling and explaining to the woman of my custom install on the back of my bus, she said two new replacements were on their way and for me to just trash the flickering ones. Great service from both pplmotorhomes.com and Bargman.
The Valley hd convertor was found for around 40 bucks but ended up getting it from Amazon for 24.00 + 6 shipping.
I should have everything by the weekend and will update my results!
Thanks for the replies!
