How To Repair Motorcycle Turn Signals

LEDs have a substantially lower wattage (power consumption) than conventional incandescent bulbs. If one plow bespeak bulb blows, the other turn signal on your motorbike flashes much as well fast – something which you will no doubt have experienced (By law, plough signals must flash at a rate of not less than lx, and not more than 120 flashes per infinitesimal). This is because the flasher has lost half of the "load" which keeps it at the right tempo. The event is exaggerated if, for example, you replace two 21 watt stock turn signals (one per side) with two LED turn signals, each rated at 1.v watts. At present the load on the original flasher is only iii watts (2 10 i.v) instead of 42 watts (two x 21). Generally speaking, this won't work.

There are two ways to solve the problem: Yous either install a special load-independent LED flasher relay, or you lot "fool" the original flasher into thinking the LEDs take the right wattage by installing electrical resistors.

Vital for the relay: correct polarity

Vital for the relay: right polarity

Replacing the relay is the simpler selection, but is only possible nether the following weather condition:

The motorbike cockpit must have two carve up indicator lights for the left/right turn signals, non a single combined calorie-free
The motorcycle must not be fitted with a turn signal beeper or hazard alert flasher
The original relay must not be integrated in a combined unit (you can recognise a combined unit by its three outgoing cables)

You can utilize our cheap Universal Relay for LED turn signals if your motorbike meets all three of the higher up requirements. The slightly more expensive Kellermann Universal Plow Indicate Relay is uniform with most hazard warning flashers, plow signal beepers and simply a unmarried indicator calorie-free (items 1 and two above).

If your motorbike does not comply with items 2 and 3, we tin can offering yous a manufacturer-specific plug and play relay, which fits the original connector or port. Unfortunately, nosotros are not able to specify the relay you require for a specific motorcycle model. Delight go to world wide web.louis.eu and enter "LED flasher relay" to see what relays are available, and compare these with your original relay. For Suzuki models, for example, nosotros can also offer you lot the combined relay unit with 7 contacts.

Relay

You must ensure that the polarity of the relay is right – incorrect connection will immediately impairment the relay electronics and void any manufacturer's warranty. Even if the organization of connections is the same as on the original relay, the polarity may still be dissimilar. Always bank check the polarity with an LED test light first (to do so, follow the flasher installation instructions).

If the plug-in connectors practise not fit, it is relatively like shooting fish in a barrel to make adapter cables to save you having to cut off the original connector on the wiring harness.

Many modern motorcycles are not fitted with flasher relays at all. Instead, they are integrated in the central electronic unit of measurement. In this case, you accept no choice but to use resistors.

Resistors

If you are not able to operate your new LED turn signals via the aforementioned relays, yous would have to use resistors to regulate the flashing frequency (in which case, you need to retain the original relay). Almost all the turn signals in our range will function with the original flasher relay in combination with the 6.8 ohm resistor.
