Roadmaster Hy-Power Diodes

Speaker 1: Today we're going to take a look at the Roadmaster heavy duty Hy-Power diodes for a quantity of four. Now, this will allow motor homes or RVs to power the lights on the tow vehicle without power feedback. The diodes will permit electrical current to flow in only one direction, from the motor home to the car, preventing any electrical feedback and the damage that it can cause to the tow car's electrical components.This part is for a quantity of four diodes with the 12 spade terminals included to hook this up. It is a heat sink design on the diode and this does reduce wiring hassles. It's a trouble-free operation. It does include detail wiring instructions on the back here, and the maximum load is 85 amps per diode.
That should do it for the review on the Roadmaster heavy duty Hy-Power diodes for a quantity of four.

These things worked perfectly for my needs. I used one on my 4500 Chevy Kodiak air compressor for the air ride seats. I wanted to be able to turn the compressor on/off without starting the truck, and still have it run when the ignition switch is on. These diodes allow that to happen. I also plan to add one to control the reverse lights. It will allow me to use the reverse lights when I load things in the nighttime without having to start the truck and put it in reverse.
The diodes are great, but the wiring term. should be weather seal type.
I have used these in the past so when i got a new tow vehicle i bought them again.
They make wiring up the lights on a tow vehicle a snap. I have never had one fail.
Works as expected. Only problem plugging electric to car sometimes not so great .Overall the Sterling setup is wonderful .

Worked great as it should ,some times plug elec.lines not so good
I installed these diodes on my wifes 2006 VW Jetta TDI to isolate the signal and tail light system from my tow vehicle. The system works as planned and the quality of the parts are excellent!
VW/Audi products are notorious for system glitches when you drive the stock lights with a tow vehicle. I routed standalone wires from the front bumper mounted bulkhead plug to the rear of the car down the inside of the drivers side rocker panel and into the trunk area.
delivered on time
i installed this product in my golf cart because when i have to load the golf cart onto the trailer to take it to get repaired i can connect the golf cart to the truck and the trailer lights to the connecter at the back of the golf cart so that all the lights work
perfect for my project -- using to tie flood lamps to rear of fire apparatus to use in conjunction with back up lamps and separately use the floodlights to be switched at the back of the apparatus
Great product and awesome service!
Easy to install in-line of your towed vehicle. Use your toad's own lighting and eliminate magnet sets or additional lighting installs. As easy as wiring a trailer. Make towing your toad as simple as possible. You owe it to yourself.
The base plate is easy to use and looks great on our MKX. The installation videos are very detailed and precise.
Diodes work as designed. They eliminate additional lights and prevent the need to drill a hole in the tail light assembly. I used these on a previous vehicle and they are still problem free after eight years.
Always a pleasure to work with this company. And this time Alyssa was big help. Thank you.
easy to install
I've used this product several times over the years and found the best price for this quality product here at Etrailer.com. The service was great with fast shipping and no damage to my items.
I'll definitely buy for them again.

Fair price, delivered as agreed on time. Would buy again from this vendor.
Only reason I did not give this five stars is that I have yet to actually hook them up in the wiring system to enable my factory lights on the towed vehicle to be operational when taken on a trip behind my RV.
Installing Baseplate an wire tailites for towinginstructions were great,the plate fit very good. The diodes work fine but wireing a ford edge for towing was hard an room for the diodes back of the tailites was very limited .I would very highly recomend your products
Roadmaster makes great quality products, and Stacey A is great to work with!
Wired up 2012 Jeep JKU for towing behind RV. These 4 diodes worked perfectly! Watched trailer video, it was easy.
Shipping was fast, product worked as ad vertised.
This was much easier than I anticipated. The instruction video of my car was exactly my model and clearly showed every step. Even my wire colors were all exactly the same in the video. I’m impressed.
These little beauties perform exactly as described. e trailer is a great company to deal with. I highly recommend them!
This is a solid product. The package had sufficient instructions for installation by someone who had never installed the diodes before.
Product looks like good quality. Seems to be plenty of instructions on line to assure a successful installation.
I use these to wire my tail lights on my cars to work with my motor home. Have used these on my vechicles since 2002, never a failure.
