    Driving lights on Tiguan

    Has anyone fitted a LED light bar to MY 2018 Tiguan? Is so how was the high beam wire tapped into for the relay to operate the driving light? Separate switch to operate LED bar to turn off whilst on high beam will be installed.

    Simple matter to tap into the High Beam globe positive; to relay coil positive; relay coil negative to inside to switch; to Earth....and most importantly the lightbar is low enough not to influence the forward radar behind the front badge.....

    Does tapping into High Beam interfer with the Can Bus system therefore can show faults with the computer and lights?

    If you only receive the 12v feed to trigger the circuit from the headlight circuit (common practice), but draw direct from the battery (fused), there shouldn’t be an issue.

    I answered this in another thread and before that few weeks ago when the same question was asked. In a Canbus controlled vehicle a normal relay system cannot be used at all. Installing a light bar or driving lights

    Then someone asked why it was needed and I answered in the same thread.
