That's why I added a relay for the H4's.
The kights switches are not the best - overhere in the Netherlands the
original 1971 type is nla, so I had to put a later type in.
When switching to H4's, do this including a for these lamps suitable lamp
unit.
If not so, you'll surely blind the other traffic.
Overhere H4's into a "wrong" lamp unit is reason for MOT test failure.
Cheers,
Hans
'71 BGT
