hi there i am looking for some help with an ongoing rc car racing project . We race rc cars with cameras inside using video goggles to drive as from the car . we all have lights fitted and sometimes race at dusk and came up with the idea of fitting brake lights which would help enormously in racing . question is how to activate the leds , we have looked at reed switches and tilt switches so far but neither seem to fit the bill perfectly . Has anyone any suggestions as to how we might go about it . many thanks . Nige
