They're a direct, push-in replacement for wedge bulbs. Just pull the original bulbs out, push these in, turn them on and if they don't work turn them round.
However without a bit of very minor surgery to your bike's wiring these
will stuff up your turn signals (unless they're doing something really tricky they're not telling me about). Let me explain...
Vehicles that have two indicator warning lights don't have a problem with LED replacements, however the single turn signal warning light in our bikes does. It works by connecting the left hand signals to one terminal of the warning light and the right side to the other terminal, like this:
When you signal left or right the side that's NOT on acts as an earth for the warning light. Due to a traditional bulb's resistance this works just fine. LED's have a much lower resistance (as demonstrated by the need for load equalisers when using them on the exterior turn signals). This lower resistance means that the turn signals will see the LED as a dead short circuit between left & right. The upshot of all this is when you signal left or right ALL the turn signals will light up like hazard lights.
What you need to do as mentioned earlier is a little electrical surgery. First you need to get a couple of 12V power diodes (about $0.30 each from any electronics place). Then:
- cut off the turn signal warning light
- connect the cathodes of the diodes to the left & right wires
- join the anodes together and connect them to one side of the warning light
- join the other side of the warning light to any earth wire (there's one on the clock/tacho connector)
You should end up with something like this:
Even if you don't use the LED's this'll make the warning bulb slightly brighter (
very slightly), and if you do my
hazard light modification the warning light'll work with the hazard lights.
