2 x H4 male to DT female (connect a 3 wire harness to a 2 wire light)
2 x H4 male to DT female. This is for vehicles with Hi-Lo lights that will be converted to a single beam light with integrated DT connector.
Example on some JD forage harvesters, 2 of the top cab lights are Hi-Lo beam lights, when using the Thomas HP-5 or the LED-6075, we no longer have a Hi-Lo beam light, and only need a 2 wire connection.
