intresting......so that would be the super slims then

it seems that this one is more decent and easy to install with plug-and-play power cables....

They are all plug and play ;)

Good price.

there are still some single beam hids with relay harness....
cos some of car headlights can not work steadily without relay harness ....
 
I use a relay harness, cut the interference i got, also i like knowing the ballasts are getting a good voltage, not from some 9+ years old wiring ;)

what kind of interference did u cut by relay harness ??? once after i installed my VVME slim hid kit 43k , there was a little flickering then went away after seconds... and sometimes there was some noise from the housings so i use relay to hook up the ballast then everything work normally
 
To be honest this doesn't sound right! There would probably be too much power going to the bulbs and they'd be likely to fail! All 50w kits should have bulbs and ballasts rated to the same wattage. I've found a kit on Ebay for £55 that is a 50w 8000k H7 kit, with slim ballasts!


55w HIDs are an update to 35w HIDs... they are more brighter with higher wattage and generate more heat.... sometimes it might melt housing or bulbs... anyhow, i think, a relay harness can fix the problems...Relay harness has built-in fuse to protect the entire headlight electric system and prevent ballast overload due to high temperature, power spike, and irregular voltage.
