Mounting lights or a camera to a helmet adds weight in an unbalanced location which adds significant rotational forces on ones neck in an accident, making the weighted helmet much less safe than a ball cap.
Anyone who has read these threads and who believes helmets work and who still rides with stuff attached is rather silly. The key to getting a helmet to work is maintaining shell integrity during liner compression. This is a lot more likely if the helmet impacts a flat surface and the impact is widely spread. Having objects attached which can hit the ground before the helmet and concentrate the impact at a small point really completely invalidates helmet design. Rydabent is being especially silly as he claims to have been trained in safety, ***but is advocating that a safety device be used in a way that invalidates its certification.*** This is something a competent professional would never do.
Plus, yes, the rotation. Although I'd hope the attachable gizmo makers ensure these things break away relatively easily under a glancing hit.
