Recently i purchased facelift headlight’s for my CRV gen II ’02, the fit perfectly only I made a mistake in connecting them.
I assumed that the H4 connector, which consist of 3 contacts ( –negative +low beam and hi beam+ ). The h4 bulb consists of two different “glow wire’s”
Which both burn separately by using hi end low beam. So I thought that it was easy.

However, after connecting and measuring it appears to go a bit different.

By using low-beam the hi-beam light burns weakly (and I measure 6v) and even the light on the dashboard burns weakly.
So I thought I made a mistake but any other configuration makes it worse.

At first i assumed that i connected the - mass/negative of on of the two light’s on one of the 2 + hi/low-beam connectors
When I re-measured white one of the lights in the low beam position of the switch, I measured +6v whiteout the light connected +12v on the hi-beam connector.
when I switch to hi beam the same wire has 12v en non on the low-beam wire

So the two h4 connector share a wire ore have double (phase) positive/+ connection??

My lights are off I’m totally lost white this one.

 

Hi, did you ever get an answer to this one? My prefacelift lamps are getting hazy and need replacing and I too am wanting the facelift lamps.

 

Problem salved!

The Mass in the H4 connector is switching from position when you switch from hi to low beam.
As an example
Hi-beam
cable 1 +
cable 2 +
Cable 3 -

Low-beam
cable 1 +
cable 2 -
Cable 3 +

From the 2 H7 lights I connected the shared cable from both of the lights to the cable witch always have 12v+

The -/mass/ground/negativ is shifting not the + in the H4 connector.

 

Don't suppose you have any photos to help me understand this do you?

 

Maby this helps?
