Dim Near Side Headlamp

Ok so Ive just fitted new bowls, new headlights with LED side lights fitted inside the lens and Wipac Spot lights on the A bar. Followed all instructions to the letter. Checked all connections twice and off side works a treat however near side Lamp is Dim lacking serious power. Gets brighter on full beam but still dimmer than the off side.
Have disconnected the spot lamps and put back to original connections and still it is dim.

The spotlights dont work at all.

Ive checked all fuses and all ok. Can anyone offer any advice as to what I have missed.

sounds like an earth problem to me

if its a disco you need to bridge a new bit of wire to that headlight replacing the earth wire

( if memory serves me correct its the black one from the back of the bulb connection )
