Can I use this as my only daytime running light?

No. It is a decorative strip with no optics or certification. Treat it as an accent and keep your factory DRLs and headlights as the legal lighting.

It takes 12V, so wire it to a fused circuit that switches with the ignition, or add a relay and switch. Do not tap a constant live wire or it will drain the battery.

Can I cut it to fit my hood?

Yes, most strips of this type can be cut at marked points. Seal the cut end with silicone so the IP68 rating holds.

Will it survive car washes and rain?

The IP68 rating covers water immersion, but only if the ends and any cut points are sealed. Check the wiring entry for water ingress after washing.

Does it fit any car, truck or SUV?

It is universal, so fit depends on your hood shape and length. Measure the run you want first; 180 cm is long enough for most full-size hoods.

Is the adhesive strong enough on its own?

Usually not for long. Clean the surface, use the included clips where possible, and add silicone or 3M tape at the ends to stop lift from heat and vibration.
