If you're running any LED bulbs or halos as indicators, you're going to wanna get an LED Flasher. This will ensure you don't get the frustrations of installing new indicators and then finding they blink a million times a minute. Or worse, don't blink at all. NOTE 1 - If you use our standard halo as an indicator, you will need an LED Flasher. NOTE 2 - Some cars have a separate flasher for the "Emergency Flasher" switch. Check if you car has 2 flashers, and make sure you order 2 of our LED flashers so your Emergency Flasher works properly with LED indicator bulbs/halos. Our 2 pin LED Flasher is plug and play for your classic car. It has these unique features which are designed keeping the classic car owner in mind: Makes that familiar clicking sound (most LED flashers are annoyingly silent) Polarity Free (will work in your car regardless of how your car is wired) Will work with any combination of LED & Incandescent bulbs (you can run all LED bulbs, all incandescent bulbs, or a mixture or LED & incandescent and our flasher will still work!) Will work with any number of bulbs (even if your car is lit like a Christmas tree!)
