Review on Alla Lighting CSP Vision LED High, Low Beam Conversion Kits for H8 H9 H11 Bulbs (off-roading), Fog Lights, 6000K~6500K Xenon White with 8000lm Xtreme Super Brightness – Premium Replacement Upgrade by Michael Tucker

These lamps have been working perfectly for 2 years. A good beam, wide, bright but does not blind others. However, I thought they would last longer. One started flickering a few months ago. He fiddled with the wires, twisted them and sometimes tidied up for a while. Now something else has started. My wife drives home from work every night. Don't risk it and replace them. If you do well with 2 years of use you won't be disappointed. I installed it early May 2018, now early July 2020. It has been flickering for about 4 months now, then goes off, then goes off. Perhaps this is the norm for these lamps. It was my first experience. Hope that helps.
