I have led bulbs on my brake, Need I to use resistor for it work ?

The brake light module works on all brake lighting. I tried it with a regular and LED light. Both work just as well. Remember though by making the bulb flash more often than usual bulbs or LED's go out sooner than later/called over usage. Everything has a lifeline. I drove around today and I tell you people sure take notice to the flashing third light. the majority stayed off the rear of my vehicle. Good luck

Probably the easiest thing to do is get a t/s flasher for LEDs. Got mine at orieleys auto parts. Just swap the flasher and your good to go.

I installed these with no problem, no resistor. I wired mine to the tail lights so they are on all the time as rear side marker lights, same as the previous two answers. I used plain old crimp connectors.

It didn't work for me with normal bulbs! I had to send it back. They responded quick and returned my money. I just used diodes on on the brake lights only on the towed vehicle. That worked good for me.

I'm pretty certain switching from any incandescent to LED is going to bring up errors due to the change in electrical flow. You can either try finding a set of LEDs that have the proper spec resistors built in that you're looking for (expensive), or you can buy just the resistor, and wire it up in about 20 minutes (relatively not as expensive). I have a set of these build on Honda Insight and they look great. The car just doesn't have a plate light error, so that was a null factor.

Some newer cars have electronics that detect a difference in the amount of current being drawn, in order to let you know that you have a bulb out. LED lights use far less power, leading to the false warning you have. In many of these cars the warning only applies to specific light, such as turn signals - so using them in reverse lights would be no problem. Other cars require "can bus" compatible bulbs to avoid errors, and in others, a resistor must be added to correct the problem. If you are using them as reverse lights, try to determine if you car uses "can-bus". If using them in turn signals, try them instead as reverse lights.

You need to use a 100k ohm resistor. The flasher requires a specific resistance To operate a bimetallic strip in the flasher properly. When resistance is lowered as in the case of LED's the current goes up and the strip heat very quickly thus the rapid flashing.

No they will hyper blink with the factory setup. You could go thru all the trouble of splicing in resistors which I did but they seem to fail about every two years or you could go to the parts store near you and buy an "LED Compatible Flasher Relay" I just wish someone would have told me sooner

Not necessary, connecting these resistors will create proper load for your LED light to flash normal.

Check ur bulb number of ur car.....far as continuous use yes there great led bulbs do not get hot will need resistor for hyper flasing

I would check the amps you would be pushing through it. If those lights are all LED then you should be OK.

i bought the single contact Led which was intended for brake and turn signals, the single point is positive and is for older model vehicles. if you have a 2 bulb system then you'll need an amber Led as well. the single or double post must match your systems current bulb type. my use of these Led bulbs was not for a vehicle however.

They should, but don't work for brake lights / running lights because there arent 2 stages of lights. Mine burned out quickly, I think because of wiring

You can get a relay for led light at any auto parts store that will work got mine at advance auto parts.

This works on regular automotive bulbs as well as the new LED lights and yes the brake light circuit wires thru this switch.

No resistor needed if you operate between 2.5V and 4.0V. I use CR2032 batteries (get cheap ones from Amazon). I ran 5 of these for over 10 hours on one battery. Remember--these are not just LEDs. They are LEDs with a switching controller. The normal LED rules don't apply.

no.if u want your brake light to flash don't buy this use what u have and buy a brake controller called back OFF from Kuryakyu.com or jpcycles.com find it on this site also.Even talk to tech he will walk u threw the Install.
