Installed my hid kit on my tib. Everything was plug and play but when my lights are turned on both bulbs flicker. Any ideas on whats causing it? I checked all the connections and everything is good.

 

First thing I would check for is proper voltage at the ballasts

 

The ballasts themselves could be going bad.

 

I installed HId's on my buddy's 05 Altima, the driver side flickers as it heats up, once fully bright the flickering is not there. This was some time ago, since then the ballast on the passenger side died so he ordered up some more ballast and we replaced both. I thought the flickering would go away as I assumed it was the ballast but the problem is still there on the driver side. My conclusion is that it is the bulb acting up, that or cause he got all that stuff from ebay.
