Well, after installing my led tail lens bulb and finding it just isn't as bright as my standard 1157 bulb I bought a clear lens from echo cycle. The led right angle bulb was 48.50 and the clear tail lens 62 bucks american. I should have stupid written across my forehead for this one. The brake light with the led bulb is just as bright as the standard 1157 but the running led taillight is wimpy.. One thing is no filaments to break and it will last forever... I will post a pic when I get a chance, but if anyone wants a trick looking light I will sell it to them for half of what I got into it.. Seriously though I wonder if the coil output on the f7 is not as much as previous sleds..Don't waste your money on a LED tail light bulb.
