I ordered the TRS HID kit (kit where I split the headlamps myself) and when it arrived, I began the install. So far, I have had quite a few issues with this kit as delivered. I'll post all of the details on the issues and how they were resolved in more detail when they have actually been resolved. The staff at TRS have been very good to work with, but beware that the kit from TRS had incorrect connectors and bulbs for the high beam (they were going to supply a more color matched high beam bulb). The low beam harness had incorrect connectors to the input power, and the projector bracket did not fit without modifications.
The biggest issue is that neither of the HID projectors will currently light consistently. I have discussed the issue with TRS and they believe there is a batch of ballasts that have issues with firing in cold weather (its been quite cold here). They are getting a revised ballast in later this week that they will be sending out for me to try.
I'll update once I get a chance to try the new ballasts. I'm curious as to what cars others who have installed the TRS HID's have - mine is a 2008 1.5 roadster. I wonder if there were revisions to the internal wiring on the headlights between roadster versions.
I did not have the wiring issues. However the ballasts are not good. They do not light consistently. I have to try a few times before it will light up, but eventually it does work out here in California where it's been around 40F at night.
