Today I installed the WhiteNight-Backup Lighting System made by Byers Precision. The box was packed very well. It included everything I needed to install the system on my 2005 GMC Yukon XL. Included was: The WhiteNight backup system, the relocating bracket for the stock 7 pin trailer wiring harness, all the wiring with quick connect clips, Di-electric grease and the "Plug N' Go" 7 pin trailer wiring adapter, View attachment 46775 View attachment 46774 View attachment 46776 View attachment 46777 The 3 way switch, On, On with reverse, Off Inside of unit, All connections coated in Di-Electric grease First impressions: When I opened the box, it was packed very well to ensure that the product was not damaged during transit. When first looking at the outer case, enclosed hardware and instructions, I was impressed. The plastic case has nicely cut edges, not sharp or evenly cut like many other cheaply made products I have seen. The enclosed mounting hardware was nicely bagged and seems to be of a good quality. When I first looked at the directions I was pleasantly surprised, They made sense! The directions were complete and to the point. They told me that for constant voltage to my trailer plug I needed to install a fuse, then told me the location of where the fuse goes. It also contained the correct information for the wire colors that I needed to connect to.

First, I removed the stock trailer plug marked a hole in the bracket and drilled one 1/4" hole. The bracket mounts with 2 included bolts and nuts. Next, you split the light unit case in half. There is an included u bolt that mounts the back half of the unit to the hitch. It is that simple, slide the back half of the case over your hitch, put the u-bolt in and tighten it up. The case snaps back together and 2 small black plastic screws are inserted into each end to secure the halves together. There is also an option to use RTV around the case to seal it. I did do that also. Wiring: With the Plug N' Go this is really easy. You plug it into your trailer plug and the wire harness running from the plug n go goes to the system. Alternatively, you can hard wire the system in. The kit includes 2 wire clips for fast connections of the positive and reverse wires, the ground wire has an large ring terminal mounted on the end. This is what took me most of my time. I decided to solder my connections rather than use the quick clips. I soldered the two connections, wrapped them in electrical tape, reinserted them into the wire loom and taped the loom. I did have a small piece of loom laying around so I also put the wires from the unit to the trailer wire harness in loom. I also coated the connector to the unit in DI-electric grease and wrapped it in tape, because they tend to dump a lot of salt on the roads here. Wire soldered and mounted in wire loom Finished Product With Ball mounted Performance: When I put my Yukon in reverse with the stock lights, I could hardly see anything behind me. With the WhitNight Backup Lighting system installed I can see excellently! It is like having head lights on behind me. I am posting a few pics, the black pics are of just mey reverse lights.

I can't wait to load the boat on the trailer this spring in the dark! (the ice on the lake prevents this today) I only have one concern about the product. Which is not a product issue. I fear that one of my kids will try to step on it. I guess time will tell. I would like to Thank @Enkeiavalanche For the great contest, I would also like to thank Rob at Byers Precision for the generous prize! - - - Updated - - - An added note: The manufacturer states that fresh water submersion is ok for the unit. Salt water is not. Sealing the unit is to keep the salt from my roads out of the unit. I am not concerned with water submersion, if I have my 23ft boat trailer with a 19ft boat in the water that deep then I have other issues. Generally when launching the boat my rear tires don't even get wet. It is also recommended that if your receiver tube is open on the back that you close it off and seal it to prevent water intrusion into the unit. I ordered a rubber plug for it for around $4, I will silicon it and install it on the backside of the tube to seal it off. I like this product so much that I am considering installing one on my wife's new Grand caravan. Not for launching the boat but, for the added light when backing up, plus with the 3 way switch, being able to turn it on when you need added light for loading would be helpful.
