Should work for most, if not all H4 style headlights. Wire length is about 12in. This allows H4 headlights to plug into the stock ATC350X harness.

Here are the Honda bulb part numbers this kit is wired for.
34901-MC7-601/34901-MC7-601AH - 60/55w
34901-KJ9-003/34901-MN5-003 - 45/45w
34901-950-003 - 60/60w

Here's a list of machines that uses those bulbs.

83-87 ATC200X
85-87 ATC250ES
85-87 ATC250SX
81-86 ATC250R

This adapter would function for other models that use the same type of connector as the ATC350X, but their alternator might not provide enough power for higher wattage bulbs.
