Well SUPERNOVA CHROMA RGB Car Underglow Lights has been a crazy journey. It has taken about 6 months of work and 7 revisions to get these thermally stable but we did it! These are the brightest Underglow kits on the market.

Prior to this, LowGlow currently had the strongest underglow kits on the market. We loved them, but we thought we could do better.
 
Introducing our Crystal Customs MAX Supernova under glow kit. It is over 150%-200%  as bright as the current market leaders. In the image above both were around 50-60% brightness. 
 
Then our highest kit, The Crystal Customs ULTRA Supernova Underglow kit takes this to another level, by effectively combining two of the Max tier kits together to achieve 200-300% brightness!

They come in 3x variants:
Standard: Similar brightness to the current market leader at a fraction of the cost (Single Row)
Max Tier: 150%-200% brightness increase (Single Row)
Ultra Tier:200-300% brightness increase (Dual Row)
