I have forever wanted to get some 06+ bi-xenon headlights for my '04 Zed, but could never justify the price for OEM ones.
When these popped up on eBay at around £300 delivered, I thought it was worth a shot.
Came in a big box, two boxes inside
Very well packaged
First I raised the front using low rise ramps and a jack and then set about removing my lip and bumper (there is a guide on here somewhere for that)
To remove the lights, you need to unscrew four bolts as indicated by the arrows below
Then carefully lift the headlight and unplug from harness
Repeat for the other side and you should be looking at this
Once the headlight is out, remove the back cover and disconnect the ballast from the bulb, remember to unscrew the ground wire
Then remove the ballast itself, there are three screws that hold it on, don't forget the seal also.
With the ballast free, unclip and unscrew the wire connected to it.
Put the ballast and it's harness to one side and pick up your Depo headlight unit.
The Depos do not come with any bulbs or ballast, but all the wiring is in place.
You need 3457A bulbs for the indicators, D2S bulbs for the main beam.
You can reuse the W5W sidelight bulbs from your old lights or fit new ones.
You need to remove the existing grounding point by unscrewing it
Then attach the grounding wire you removed earlier
Attach the ballast main connector and connect the ground wire to it
Feed the wire to the opening where the ballast will mount
Reattach the wire to the ballast and screw into place, don't forget the O-ring
Offer the lights to where they need to go and re-connect the main harness and test that all lights work before putting everything back together.
Then it's just a reversal of the removal and job done.
