FastFlash 60 Watts Brake Flasher Tail & Stop Light Strobe 50X Fastest Preprogrammed 3 Blink Pattern Sequence - LED & ANY OTHER BULB for Cars, Trucks, Motorcycles mount 5A 12-24V

This unit works as expected with LED's or incandescent bulbs. Installation is straight forward if you can use a multimeter and have a wiring diagram. I installed mine on my 12' shadow 750. The unit is smaller than it looks, fits under my seat along the frame rail quite nicely. Wires are quite small and conductors are thin, soldering is definitely recommended over crimping on any application.

Works perfect. Installed on my third break light and still going strong after one year. Installation was easy. The instructions that came with it weren’t the best. But there are plenty of videos online on how to install the relays. Great price for a great product. It’s stopped a lot of people from getting to close to my vehicle when making stops! Everyone needs this for there car or motorcycle it could save your vehicle or your life!!

Works as it should easy to install

Mine didn't work It behaved like a straight piece of wire: Initially I connected it precisely as the instructions directed. The load -- an LED stop light 'bulb' -- Illuminated and stayed illuminated. No blink. After that, I tried every imaginable combination of loads (from the LED -- to an incandescent auto headlight0 as well as all of teh available variations with four wires and four terminals, with no discernable change: might as well been a straight hunk of 14ga wire. Surprised, cuz about a year ago, I bought a "100-A" (also Amazon) and it has worked perfectly, flashing my 3rd brake light according like the description said. So I bought 4 more 100's for my other vehicles.

The instruction manual is minimal. Don't expect to receive any help from the seller.I have middle knowledge about car electronic systems.You'll need basic electronic and general mechanical skills to install this. You will need a mechanical and electronic tool set. You will need to know how to connect wires together. This is a car. You will be altering the way your brake light functions. If you don't feel comfortable, buy this and have a good electrical mechanic install it. On my first try, I had no response from my 3rd lamp. I sanded the paint from one of the 3rd light connection points (the grounding wire) and added di-electric grease to all of the connection points. Success!Get one! People in my town (central Florida) are installing these and it seems to make a difference in how you are noticed.I notice blinking lights more than I notice static lights.Oh, one last thought: In my case, this was much easier to install at the tail lamp rather than the brake pedal. Two wires vs. Four.

I have a few Bikes so I ordered both the Fast Flash and XP-60 simply because they do not explain the difference in the two, so I will do it here.The XP-60 will allow your break light or any light to flash when activated. The Flash sequence is slightly different or seems to be slightly different than the Fast Flash. The XP-60 has 1 quick flash followed by 3 quick Blinks, followed by 3 slightly longer blinks then a nice steady on. The XP-60 is in no way a frantic flasher, it is noticeable and will get the attention of the people behind you, just not startle them. The Fast Flash, is just That a FAST very Fast Flash. Activate and it is very Rapid (2-3 times faster then the XP-60) 3 burst, then 3 flashes much like the XP-60 first the flashes, then it Stays a strong steady break light. The Fast Flash is a Frantic attention getting flasher!!!! It will wake people up behind you!!! It will annoy them for sure if they are following you in steady traffic.Installing them was very easy, Follow the fire harness from your tail light to where it connects into the main wire harness, you will be able to unplug your tail light there. You should have 3 wires, power, ground and break light. Power is for the constant on part of the tail light, the break wire is the one your looking for as well as the ground. The Flasher unit is clearly marked In and out on both sides and has 2 wires on both sides. Hook the (+) to the power wire and the (-) to the ground. Turn on the key to the bike and your light should look normal. Squeeze the break and you should get the flashing sequence before it stays a steady on bright break light. I add two small LED marker lights below my plate, so they will flash in and stay steady on while my break light will operate normally. So you can add up to 60 Watts of lights with these little boxes, or a bunch led lights (because they use almost no power) The whole wiring process is super simple and will take just a few minutes if you are just using your break light. If you are adding lights like me, then of course it will take a bit more time. They do supply you with some really strong double back tape to mount this tiny box where ever you have room. The box size is very small, maybe 1/2 to 1/3 credit card and 1/3 inch thick. it is smaller than it looks, so you will have plenty of places to locate it, even on race bikes. They work well, I will post a couple of videos when I get them both hooked up on the bikes. Again I added two marker LED's to my bikes, which I purchased from Superbright LED.com. They also sell here on Amazon.

works GREAT
