yup exactly as Rnlcomp says....
i had hyper flash shortly after getting my truck last year and couldn't figure it out, even had a friend sit and press the brake, tun on signals evey thing... nothing looked burned out then I noticed one tail light looked dimmer..... popped it out and sure enough, one bulb was out.
