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.
Average Customer Rating: 4.9 out of 5 stars (106 Customer Reviews)
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. 656394
Wired up 2012 Jeep JKU for towing behind RV. These 4 diodes worked perfectly! Watched trailer video, it was easy. 603740
I used these on another vehicle and another brand on a different vehicle, these were far superior the other brand gave me lots of trouble. 434876
Does what it's advertised to do. Thanks for the quality! No worries. 307306
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. 297661
straight forward instructions, worked w ell 285900
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. 273306
Happy with the product. 271078
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 248953
These little beauties perform exactly as described. e trailer is a great company to deal with. I highly recommend them! 221501
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 171578
Just as described!! 153168

Received timely and good condition. 100915
This is a solid product. The package had sufficient instructions for installation by someone who had never installed the diodes before. 97805
Product was exactly as described and the shipping was very fast. Got the item as stated. 96123
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. Tom D. Grants Pass, Oregon 91376
Product as advertized. Arrived on time. Well packed. 63245
Great Service, Great Prices and quick shipment. 45268
Easy to install and works great! 21687
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. 13170
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. 7227
Installing Baseplate an wire tailites for towing instructions 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 3751

Installed 6 of these to wire up my 04 Honda CR-V as a Toad. They work great so far, lights come on from either the CR-V or the RV. Nice that they come with the terminal lugs so all you have to do is strip and crimp the wires. 223175

I needed to charge my tow vehicle battery by taping in to my tail lights on my motor home. This will prevent The tail lights on the tow vehicle from feeding from its own battery. My break buddy was depleting the tow vehicle battery on long trips. Solved my problem! 524458
Working great, no problems

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. 655651

Needed to set up a circuit to activate my reverse lights on the trailer to light up the loading ramp. This worked great to keep the power from backfeeding into the car. 148921

Ordered a diode for a project on my RV and it worked out fine. I just wish the price was much cheaper for such a small part. 402096
Ok
Jim - 07/06/2018Review from a similar Roadmaster Hy-Power in Accessories and Parts
This is a little premature to give a product rating. I will say that the diods iordered arrived sooner than expected. After reviewing the options for wiring a vehicle to be towed behind a mtrhome this is the way to process. Thank you, Jim 464083

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.... 232182
Review from a similar Roadmaster Hy-Power in Accessories and Parts
Fantastic. The advice received from E-Trailer was perfect. The Diode was exactly what I needed. Small, inexpensive, and very effective. The adhesive back and included connectors couldn't have been a better fit. Needed this to prevent backfeeding of a Motorcycle Lift Battery in my pickup from powering the truck. Truck required a disconnect of the negative battery cable before towing behind a motorhome. 332628
Review from a similar Roadmaster Hy-Power in Accessories and Parts
I was amazed to learn that similar to plumbing, you can put a one way valve in a 12 volt wire as well. One of my batteries was not being charged when our RV was plugged in and to make sure I did not run down my engine battery I installed this diode. Simple and came with connections ready to be hooked up. Arrived pretty quickly too. That you Christina J for one on one over the phone help. 500181

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. 264095
Over a year and still working well. High quality.
Ron - 06/23/2017Review from a similar Roadmaster Hy-Power in Accessories and Parts
Using this to trigger a 12V device if one or both 12V sources are on. Essentially I need to turn off a device if my engines are running. I wanted to make sure that if one engine was not running it would still trigger the device. This worked perfectly because it isolated the input sources so there is no conflict when both 12V inputs are on. Lots of uses, sturdy construction - simply perfect! 254347

Not too big so fitted in tight space well. Found crimps supplied on the loose side. Used other type which were more secure. Replacing the diodes l fitted earlier l found the problem l was looking for. Cable soldered joint. So now l,m all set for a while. This diode set looks very robust. 396322

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. 517440
Review from a similar Roadmaster Hy-Power in Accessories and Parts
I always have trouble receiving deliveries because I have a postal address that doesn't accept FedEx or UPS and a physical address that doesn't accept USPS. The website doesn't specify the shipping method, so I sent a note to customer service. The rep personally oversaw my shipment so that I got it quickly and at the right destination. It's that kind of service that keeps me coming back to etrailer.com 246724
