Our Hideaway Covert LED range may be super discreet, but with two large LED chips per lighthead they certainly get noticed! These are E-marked, CE and ECE EMC R10 approved. A small 13mm hole is required to install these lights, they can be easy fitted into vehicle headlights / rear light clusters with the pre installed 3M self adhesive gasket (screw fitting is also an option, screws not provided).
