Re: DIY Hazard Light/Parking Light

Though i am not a technical person i tried doing this method on my hero honda super splendor and it didnt work. Found the input supply and indicator cables, and shorted the left and right indicator wires, the indicator didnt work and the relay didnt tick tock but had a krrr sound. I thought something went wrong and i might have overloaded the relay. But on removing the load the indicators began working. Then researched a bit and found some technical information on diff types of relays.

Earlier bikes and cars used to come with electromechanical relays which used to make sound while operating. they work based on the load applied and hence in my 2006 model super splendor bike if one indicator light fails the other doesnt work or flash at the specified rate. But in modern bikes they must have replaced them with electronic relays which dont make tick tick sound when operated and are independent of the load applied. Hence for people having electromagnetic relays this may not work.

We may need to buy an electronic relay or rather an advanced relay highway flasher like this

This has different patterns and works well.

Re: DIY Hazard Light/Parking Light

Respect your effort and the time spend on this. But using this lights in heavy rain will be a stupid decision. These lights are called Hazard lights and its only used in case of Emergency braking or parking or in other emergency situation. Not for rain or Fog. This will confuse oncoming traffic. You can either use park lights or DRL's for this purpose or fog lamps in case of fog.

When you switched on your hazard lights in rain or fog and want to take a lane change, you put the indicator, But it wont effect as both indicators are blinking. Behind vehicle wont come to know about your lane change and can cause accident, and roads are slippery too.

Re: DIY Hazard Light/Parking Light

everyone here uses hazard lights when in fog or heavy rain. i know its not a good idea but somehow it became trend now. ppl has accepted this

agreed. but again, ppl dont value indicators here. if they want to cut the lane, they will. you cant stop them. so its not unexpected for me if person ahead of me in left lane suddnely comes to mine.
while changing lane, rider can switch the connection off and will one set of turn indicator where he wants to shift.

Re: DIY Hazard Light/Parking Light

If you are also doing like others who does not value rules , whats the difference of you being a Biker? You are inviting trouble for you as well as for others. Its nowhere written that if one is not putting indicator you also should not. May be If you put indicator , by seeing you some other will also learn to put. Try to learn value of the rules and ride safely. Its always for everyone's safety.

Re: DIY Hazard Light/Parking Light

no where in my post i said i turn or switch lane WITHOUT using indicators, did i?
neither i promoted or praised ppl not using indicators, did i?

i just had accepted the fact that its trend to use hazard lights in heavy rain/fog both by cars and motorcycle riders. and person posting DIY can switch off the bridge and use the indicator in the direction he wants to move if he is riding in heavy rain/fog and wanted ti switch between lanes. also dont ever expect others to turn after indicating for your own safety. thats all i said in previous post.

i request you to not to assume things. please read twice if you want to reply on some text.
i am assuming one thing for good, you might have been in hurry/watching movie/talking to someone while reading my reply and posting your views on it.

Re: DIY Hazard Light/Parking Light


Ok, My bad. My mistake. the fact is I dont encourage anyone to break rules, I might ve been become little aggressive while writing the post....

Re: DIY Hazard Light/Parking Light

Is it possible to do all this without using diodes?
Thank you.

Re: DIY Hazard Light/Parking Light

If you use a DPDT (dual-pole) switch, diode can be eliminated.

Re: DIY Hazard Light/Parking Light

Follow step 1 and 2 completely as given by Gaurav.

After that open the bike's headlight assembly. There will be 2 bolts on left and 2 on right side near the top of shock absorbers. Use a T rod to open them up. There is another bolt above the console, remove that too. Slowly detach the headlight assembly and let it rest on the front mudgaurd. You may need to unplug the digital console for easy movement inside the headlamp assembly.

Now from the hazard switch you made in step 1, two wires will be coming from the diodes. Attach one of the wires in the plug socket of one of front indicators and other wire in another front indicator.
Now for the third wire of the hazard switch, you have to first locate flasher unit. Unplug it and attach that wire to one of the terminal and re-plug the flasher. Turn on ignition of bike and press the switch. If the indicators are not blinking then turn off ignition, unplug flasher unit again and attach the wire to other terminal and re-plug it. Now check again and you will find that the indicators are blinking.

Reassemble the headlamp assembly and you are done.

Re: DIY Hazard Light/Parking Light

Is there a way to auto activate Hazzard lights on Battery ON + Engine OFF and disable when Battery ON + Engine ON, while still keeping the Hazzard switch functional all time..?

Re: DIY Hazard Light/Parking Light

Hello sir,
Same procedure to be followed for a KTM RC 390?

Re: DIY Hazard Light/Parking Light

Will the diodes solve my problem?


I have shared the flasher relay output to all the 4 signal lights so they all blink the same time. It works normal(blinking) when engine is off. but once the engine is running, the blink begins to work like strobe light...


Please help...
