    These will be used in setting up a Towed (TOAD / Dinghy) vehicle behind my RV.These Diodes are well built with Nice aluminum finned heat sinksFrom all my in-depth research these appear to be identical to some used by well know Companies that sell Light kits for Towing behind RV’s and same used for setting up utility trailers etc.Great Value compared to others I researched

    I wild these I to our Mini Cooper S flat tow car and they worked perfectly for two RV trips so far. No issues or bugs or warning messages from the car (which is finicky about the electrical stuff). I also used them in wiring up additional exterior lights and backup lights on the motorhome. They are expensive, but very well made, and rugged.

    Items worked as they should. Price very reasonable, no sense wasting money on fancy items 10x in cost.

    I installed four diodes in the tail lamp section of my 97 forerunner to allow pulling it with my four wire tow plug on my motor home. Easy install – works great
