I've recently been faffing with my bike set up to be more comfortable on long rides. The last add on, tri bars, left me with nowhere to fix any lights so this afternoon I've cobbled a solution.

Found a piece of tubing the same diameter as the tri bars, cut it to length and then ground a rough saddle joint to give a snug fit. Drilled the ends to thread a zip tie through and used them to fix the bridge in place. Tidied it up with a bit of electrician's tape and the jobs a good 'un. Not perfect but good enough anyway.
