Thanks, is there room to put your hand in?

The adjusting screws are external and accessed straight down from the top - no need to put any hands down if the screw-driver is long enough. The adjusters are white/cream.

Watch this, not a D4 but the same principle.

It’s dual. It’s a hex and inside at the bottom of the adjuster is a Phillips mould. For this reason your philips needs to be narrowish

Thanks, the D4 light adjust looks like the LR sport video that you posted.
