Questions & Answers
Either 87 or 87a must be used to connect both lights. There isn't an 87 to one light and an 87a to the other. You can see how the internals work by searching for "relay diagram" on Google.
I'm not sure I'd put it in a place where it would get wet. It is, however, in the engine compartment of my vehicle.
It's possible there's a problem with the foundation. It happened to me as well. There was a problem with the grounding.
Selected User Reviews For KC HiLiTES 3300 12V Relay - 12 Volt
owing to the ostensibly 23-year warrantybr> They claim that the relay can handle a certain amount of power, but it can't. I know this because I've gone through at least four KC 3300 relays in the last four years, despite using far less power than they claim. Worse, thebr>lights aren't turned on very often. Finally, following extensive research, Taking the cover off the relay, the wires can handle the wattage, but with the tiny components of the relay, anyone can see that the componentsbr>themselves within the relay can't handle the wattage they claim. br>From the inside out, they corrode or burn out.
It's also sealed! My original KC relays were not sealed and corroded badly (they were installed under the cowl on a Jeep), so I had to replace them. They were only good for three years. THESE, on the other hand, are a step up. What I'm curious about is why KC had to use a proprietary relay design to begin with. At first, I ignored the wiring schematic and attempted to replace the relays with standard relays. NOPE! lol. You either have to use these or rewire your lights (which isn't a big deal, but I wasn't going to rewire the entire system to use standard relays). I had a great time.
It's what I use for my vehicle's headlights, which turn off the low beams when the high beams are turned on. This relay overrides this setting, allowing all four lights to stay on when the high beams are active while returning to normal when only the low beams are required.
Regardless of where the wiring is connected, the relay switches too quickly. In the last seven years, I've had to replace both of them three times. They last me about two and a half years. When it comes to work, however, it's fantastic.
My problem was not solved; it turned out to be a blown fuse. I mean, it works, but I think the price is a little high for what you get when compared to other external lighting relays on the market.
This was the solution to my KC light problems. Installing is a breeze.
It performs as it should for a relay.
