Trike MOT Hazard Warning problems.  Your trike will fail its MOT without Hazard Warning causing you hassle & the expense of a second test.  The solution is simple - fit a HW kit to your trike prior to the MOT.  You can do this in less than half an hour by fitting a custom-built kit.  Over 500 of these are now fitted to trikes.  You can buy this kit from eBay for £18.50, just look under "Trikes/Quads/ATVs", or "Motor-Cycles and Other Parts".  Best of luck with your MOT.  Andy C
