Caterham Cars LED Headlights - how to wire "dip" to be always on when main beam is active?

[John Vine]

Looking at this a bit more, perhaps we're over-engineering things. The simplest solution would be to move the dipped-beam wire from the dipswitch throw-2 output terminal to the dipswitch feed:

This would give you permanent dipped beam with switchable main beam.

I think JV’s diagram was deliberately from the driver’s point of view - with the headlights being ahead…. 🤔😀

Thanks Jonathan. I took the pic on my  Samsung S9 Android (I junked the awful Nokia 2.2 a couple of months ago). I've just taken it again portrait and got this:

So, it doesn't seem to be an orientation problem.

yep JV last one is the obvious in the same way sidelights are wired ...

Be careful you dont overheat the units though the heat sinks will only be designed for either or not both, you might want to measure the temp on the unit for prolnged periods on dip only main only and then both, dont want thme going pop on you mid journey.....

Thanks, Neil.  A pointer for Anthony...

Great to see all this thanks. Heat warning noted. (Away at the mo)

If excess heat proves to be a problem with prolonged use of both beams, you could add an extra switch to control whether or not the dipped beam is to be activated.
