This is ET making four passes, first with low beams, then high beams, followed by high beams with running lights and finally with modulator. ET's ST1300 has been modified. The pair of 45W halogens have been replaced with 65W PIAA bulbs, and a relay takes headlight power directly from the battery. The lights are about twice as bright as a stock ST1300. The videos were shot on a very bright summer afternoon. See it on Youtube.com.
