Exclusively designed, US patent pending front/rear LED turn signal lights with no load resistors required and plug-and-play installation (no hyper flash)
ONLY good for front or rear AO (Amber-Off-Amber-Off) type turn signal light use (Can't not be used for both front and rear together)
Bulb size approx: 0.8'' x 0.8'' x 2.23'' - Powered by 35 pieces of 0.75W 3030 type SMD LED diodes with a gorgeous amber glow, true 21W output, just like OEM 7440 W21W incandescent bulb, but with 3x brighter lighting output (1000 lumen)
Warning: Replace EITHER the front or the rear turn signal bulbs, but not both, otherwise you will still get hyper flash; these replacement bulbs will not hyper flash on turn signal lights, but are NOT "Error Free" in European cars; There is a protection IC inside, so each turn signal cycle cannot exceed 8 minutes; You CAN'T use it for constant light up such as driving lights, daylight DRLs
