Turn signal light flasher quandry

A few weeks back I dumped my K4 Manstrom in a little mud bog (submerged tree branch took the front end right out) which naturally cracked the eggshell thin front turn signal on that side.

Today I decided to ditch the cheesy factory turn signals in favor of some flush mount truck cab marker lamps procured from Pep Boys. Problem is that the lamp assemblies are not large enough to accommodate the 21W 1156 bulbs that the OEM eggshells have, and the stupid combination flasher module and kickstand switch relay doesn't like the lack of current, so it flashes too fast. I've even replaced the wimpy low wattage bulbs in the marker lights with some 10W euro bulbs, but even that is not enough to keep the (K4+) flasher relays happy.

I've seen where folks have split the wiring off of the OE combo relay in favor of a dedicated flasher, especially for LED type applications. Just curious if anyone has ever speced out a flasher module for the stock 21W rears (protected by my side cases) along with a 10W front bulb.

By the way, the cab lights look much more streamlined. But are a bit harder to see from the front, being tucked in so tight to the headlight. Maybe what I should do is to just parrallel a second set of lamps up on the front somewhere for the added conspicuity.

So nobody has any words of advice on a flasher module?

If the k4 already has a flasher module why would you need a secondary one that came with the marker lights....?

I guess I didn't make the situation clear enough.

The new marker lights use lower wattage bulbs, 10 W vs the stock 21 W on all K4 or later models (the K2 & K3 used 10 Watt turn signal bulbs all around, so would not have this problem)

The stock flasher relay senses the lower current draw and flashes too fast, which will not pass state / DOT requirements. This is supposed to be a safety feature of the relay, to alert you to a blown out signal bulb.

I will just get a universal flasher module that doesn't care what the load is and re-wire to not use the stock flasher relay.

An LED compatible flasher will do the trick. They work independently of the load. There are units that are a direct replacement advertised on Ebay, usually for the SV650 which are the same. I had one die after a few minutes of use but most report no problems. A cheaper alternative is a standard unit but that takes some work with wiring as the stock module also has the side stand safety relay in it.

How do I connect an LED flasher in place of the OEM unit?

Chances are replies were less than forthcoming because the thread title is about a brake light flasher rather than a turn signal flasher.

Thanks for the links greywolf. I was able to pick up a 2 wire electronic flasher module at VIP auto for 10 bucks. Rated for from 1 to 8 bulbs. Installed with the help of your link to find the right wires. Works like a champ.

Cheers!
