FeaturesCompatible with LED bulbs.Prevents hyperflash errors.Simple swap for original module.Direct fitment and proper sizing.FlasherHyperblink Fix. Why do you need this module? When your factory turn signal bulbs go out your vehicle's flasher senses that less power is being used and it will blink the turn signals quickly to alert you. Since LED bulbs use less power you get the same fast blinking known as hyperblinking " even though the LEDs are functioning just fine. Basically your car thinks the bulbs went out!To slow down the blinking to regular speed you can add resistors to increase the circuit's power consumption again. However whenever possible replacing the flasher with a module like this is the easiest option. Simply unplug your original flasher from under the dash and swap it with this one to prevent hyperblinking.Quality. The flashers distributed by Diode Dynamics are produced by industry leaders such as Novita. Watch out for generic cheap flashers as many are slightly too large and may not fit properly in the socket."Shipping Notes

BO - stinky!
Color: White, Size: Medium
Shirt itself fits great and has a soft almost velour feel to it. Ribbing nice and not itchy. However, it arrived with the most disgusting baked-in body odor smell, as if someone had sweated heavily in it. Unsure if it’ll be able to be laundered out.

Buy it
If you're looking for a comfortable thick and nice turtle neck this is the one. It's nice and form fitting nice weight to it to keep you warm. But not to thick that you cant just wear it on a regular sunny day if you wanted. The design pattern Is also very nice. Can dress it up or down. I bought the black and then immediately bought the rust orange color for my friend once he tried on mine he wanted one immediately so I gifted him one. He loves it. Definitely worth the buy. Excellent quality. I bought a Large 5"11 165lbs
