Roadmaster Hy-Power Diodes
Diodes permit electrical current to flow in only one direction - from the motorhome to the car - preventing electrical feedback and the damage it can cause to the towed car's electrical components.
Features:
Note: 4 Diodes are required for most applications (1 left turn/brake, 1 right turn/brake, 2 for tail lights - each side).

Speaker 1: Today we're taking a look at the ROADMASTER Hy-Power diode. Now, this will allow motor homes or RVs to power the lights on the tow vehicle without power feedback. The diodes allow electrical current to flow in one direction. So, that'd be from the motor home to the vehicle or to the car. This prevents any electrical feedback and the damage it may cause to the electrical components.This is available in a variety of quantities, so you can get a one pack, a two pack, three pack, or four pack. All options are available at etrailer.com.
For a one pack, use part number RM-790, for a two pack, use part number RM-792, for a three pack, use part number RM-793 and for a four pack, part number RM-794.The spade connectors allow for easy, trouble free, wiring connections. Also, on the back of the packaging, it has detailed wiring instructions, so that's really going to be helpful. So, when you get these, please do not discard the packaging because it has the nice wiring instructions on the back side.The aluminum heat sync helps prevent over heating. The self stick pad on the back allows for easy and secure mounting. Maximum load is 85 amps per diode and please note that four diodes are required for most applications, one for the left turn and break, one for the right turn and break and then two for the tail lights, one per side.That's going to do it for today's look at the ROADMASTER Hy-Power diode..

Used on a trailer to add a strobe function on my existing trailer lights, and not backfeed to the truck. Has worked great for over a year now, in snow and rain it hasn’t failed.
Good product with excellent service! I can now use my reverse lights as work lights without back feeding my truck. Works great to correct those who have a have a habit of driving behind you with high beams on....
I purchase these to set up my toad (CR-V) with the Road master 7 to 6 wiring kit along with the 2 back into 3 wire module to allow for me the use the turn signal lights (Yellow) operate separately from the brake lights so that the toad lights all work as they were set up by the manufacturer. This way also allows you to avoid having to buy the brake light relay if your vehicle brake lights are energized by the mechanical function of your braking system. Your overall cost is relative and as stated all of your lights work instead of the typical stop/tail/turn signal bulb on each side.
Can use these for allot more than just a towed vehicle. I used them for my loading lights on my trailer to help with backing the trailer at night. Just pulled reverse power wire from 7 pin to original cargo light wiring. Works great.
I bought these diodes to replace two that the connectors corroded to the point the taillights on the towed vehicle wouldn’t work. The old ones lasted 6-7 years which is pretty good. When I hook up the new ones I’m going to put some waterproofing over the connectors.
Bought these diodes formy license plate lights on my toad. The wiring kits only come with 4 diodes which would not allow the license plate lights to be light when towing.
Product worked as advertised tail lights on my Jeep work great when towing with my RV.
Diode packaging has helpful wiring diagrams on back.
1950 Spartan Royal Mansion. Thank you for your ongoing help and wide array of products!!!
I was very impressed with the trailer.com… Not only was the ordering very simple and effective and done in less than a few minutes I received the package in a very timely manner! Also I called the office spoke with Michelle and got the best customer service possible with an additional order… I will highly recommend etrailer.com to all of my friends!
Easy to install and worked as advertised. Installed 6 diodes and Curt inverter inside tail lights vs. inside of vehicle having to remove panels. Saved hours of work.
I just installed them and they work as they should. I was isolating lighting on an equipment trailer for a brake and turn circuit. Now it does not backfeed.
Easy to install them in my old jeep wrangler for the flat towing!
I haven't installed the product yet, but it was exactly what I needed. Diodes of this type are not the easiest thing to find. Etrailer had them, and not only is their website laid out well, but the service and shipping were very fast.
I am very happy with the product, I installed them and now my lights work great.
I was very please with my customer service rep. she knew her product line and worked with me to fix my problem. Thanks
Response to phone calls quickly and knows what he’s talking about
Perfect for connecting the tail lights from my RV to my car on the car dolly.
Product worked exactly as expected. Very clear and detailed instructions. Great service and shipping as usual from e-trailer.
These diodes are easy to work with and looks great. The only issue I had with them was the self stick pads weren't great.
Product as advertised. Must wrap with tape and use dialectic grease to prevent failure of this part. Other then my haphazard initial wrapping, the product worked very well.
I needed these to wire a TOAD (tow vehicle). They have worked as advertised.
The plus is that they are quality products.
The con is that they are not cheap.
