Factory turn indicator flashers are designed to flash quickly if a bulb is burnt out. Unfortunately, the low resistance of an LED looks like a burnt-out bulb to these flashers, which leads to "hyperflash". Hyperflash isn't cool.
You can address the problem by adding resistors, or you can replace the flasher. Replacing the flasher is the right way to do it, but it's a little more expensive. Resistors can get hot and they do burn a little more energy. Okay, maybe you're not that worried about the latter. But if you want your car to think it had LED turn signals from the factory, a new flasher is the way to do it.
For the NA, we offer two options for the flasher:
- A plug-and-play version where we start with a new factory flasher and modify it. Old factory flashers can actually suffer from cracked solder joints so this is a maintenance upgrade! We know this option is a little more expensive but it takes some time to do.
- If you want to put your soldering skills to test and save some cash, we now offer the single 1M ohm resistor that allows you to modify the flasher yourself. If you do not know how to solder then we recommend you stick with the pre-assembled option.
The NA flashers can also be used with incandescent bulbs. Please be aware that if a bulb blows out, you won't be able to tell by the speed of the flasher.
Unlike resistors, which are required at each bulb, you only need one flasher per car.
