I was down to 3 out of 15 LED lights on on one side and 1 of 15 on the other side on my boat trailer lights that are 17 months old, so I sprang for new ones. Lesson learned is don't lose the receipt, but considering I had to redo the connections due to corrosion so many times that I was out of wire, and it may not have mattered. Did some research to try and improve on the corrosion problems I had over the past year and found a post about using liquid electrical tape. The only one I found at HD was spray. I thought it would be brush on, like PVC glue...anyway here's what it looked like after spraying over non-insulated butt splice connectors ...small heat shrink over each wire... http://i735.photobucket.com/albums/ww359/MariettaMike/IMG_20140125_143038_zpsove24icp.jpg[/IMG] ...large heat shrink over the whole deal... http://i735.photobucket.com/albums/ww359/MariettaMike/IMG_20140125_14351_edit_1390678550772_zpslfdgd5sn.jpg[/IMG] Hope it lasts, because it will be a bitch cutting that heat shrink off.
