I just finished this install about a hour ago. IMO, these things are AWESOME. I should have done this sooner. I weighed them on a scale and they weigh close to the same. My stock LED lights had 6 big leds on each side and these have 12 small. Maybe that's why they don’t last ? Or it's because the guys cut out there stock bulbs. I did not. Mine are wired in series and flash with my existing light turn signals. Time will tell, but 4 now I LOVE Them. Look Great in the Garage with the lights out. LOL
