I bought 2Ghozt LED Sequencers v5 (28 ch) to modify my Audi S4 B8 headlight DRLs to switchbacks. The quality of the pcb is excellent. I have yet to use them as I'm waiting on led components. I would like to see 30 pin connectors included in the pack along with some header pins.
All in all I'm very pleased with my purchase.
