hid issue with auto on/off

I followed Jay's and Kevin's advice to visit Alex at Fuzion Teknique for HIDs. I was surprised that the eurotech kit he uses doesn't have a relay. Upon further research, the xenonsupply kit doesnt have a relay either. After the install, we tested the system and heard an electrical krackle/zap. Initially, Alex didnt realize that I had the auto on/off feature. He explained that the computer instead of gradually sending current through the system, the computer sends it all at once. Alex reassured me that the prius doesn't need a relay and theres a lifetime? warranty. I drove home and had no issues.

Today, I tested the lights by rotating them from off to on etc. I heard the krackle again. I also noticed that my left light was dead. Rotating through the switches didn't help. Five minutes later after turning off the car, I restarted and the left light worked again.

Should I be worried about the left light in the future? Do owners with the auto on/off feature need to buy the hid kit with relay? Is there something that will delay the power to the bulb? And should I also worry about blowing a fuse if I leave everything alone? I have the tanabe stb installed; so its a pain to access the fuse box.

 

sfv - thanks for the advice. im wondering if i was too cheap and should have gotten the trs morimoto hid kit with the relays. Is it easy to an install the relays? Are the relays built into the wires?
