I made these for my GS. £1.99 delivered from ebay for a pair of LED strips and £3.00 for 3 scrap hand guards from Motorworks to get the drilling round the corner right. I made some templates using graph paper and sellotaped it on the hand guard, pilot drilled with a dremel than used a 7mm bit. The LEDs push in to the holes quite snugly and then you mastik them in place. Black is best and make sure you smother it over the back of the LED strip so that you don't get light shining in your face at night time. They're wired in to the side light bulb connections and have been on over a year. I definitely get noticed by cars!
