Few of us here has done Auto Lane Changing Flashing mod, where involved flashing relay replacement. Following thread provide you some information on how to access the flashing relay:

Hope that helps.

 

Thanks! Nice work you've than. 多谢🙏

 

Thx and you're welcome! Are you Chinese (or with Chinese language skills)?

 

 

 

maybe that will help. looks like the front and rears are paralleled. as long as the front signal wiring can handle double the current (since simulating 2 bulbs) it looks like that could work.

a higher wattage by itself wont exactly work, it also needs to drop the resistance in order to double the current. you would wire in the resistors in parallel, to double the current. getting a single resistor with 1/2 the resistance and 2x the wattage would be the same.

another option is skip the resistors and change the relay to one with a set time regardless of load. they make these and are simple to install. this is my recommendation since you already have the bulbs. its as easy as swapping out a relay.
something like you can also get these relays with adjustable timing, and even timing that changes as you are sitting at the corner.

another option is use these extensions with resistors. just plug in and thats it. should be long enough to go wherever



​​​​​​​theres even led turn signals with built in resistors. then you dont do anything besides change the bulb.

there is room to add resistors in the back, here are ideal locations.

 

 

most folks dont know which version of adapter to buy. theres so many, they get them and wonder why it dont fit, or it burns out the fuse.

beware theres some that look the same. people have burnt fuses, melted sockets, etc.




as for the flasher relay, if i was doing this again i would make my own relay if none were available. i bet diodedynamics wouldnt want to refer you to vleds, theres other ways to mod the relays also.
https://v-ledsblog.com/2010/12/02/ho...k-with-v-leds/ this is because i already had the bulbs
now, some vehicles wont even have the flasher relay anymore, much easier and cheaper to integrate the flash circuit into another component.


or maybe id get a turn signal with the resistor built in if i didnt have the bulbs. well, i recommend this approach for the easiest and quickest. i dont know about the actual bulb in this link, this is for the idea.

in actuality i have some of the most complicated turn signals ever. not sequential or auto flashing though.

 

 

if all you did was to parallel the resistors in one spot, that cuts the resistance in half while doubling the wattage capacity. if the lines are actually separate, then you need them on each one.

 

Has anyone had success installing both front and rear LED turn signals without a load resistor and not experience hyper flashing? If so, what bulbs did you use?

 

yes
used may bulbs
you can use bulbs with built in resistors
you can use a different relay that doesnt use current to time flashing - this is the recommended method

 

Thanks. Do you have a part number for the bulbs you used?

 

the last ones i used were this

I used them because they were switchbacks. they did have the resistor.

any 7440 should work with the relays, but do check if its wired CK or not
