For some time I had been looking at different types of LED turn signals for replacement of the original bulbs on the Tenere with an LED cluster. So, in preparation for the conversion I knew that I would need to replace the original relay with the electronic type that did not depend on the 20W load of the incandescent bulbs to function correctly. The one I selected was a solid state electronic unit and a drop-in-swap with the original, it worked just perfectly with the original bulb turn-signals while I continued my search. A month ago I happened upon the Weiser website
http://www.weiser-motorrad.com/home.htm. This company makes LED conversion kits for the OEM turn-signals used on the Tenere (and others) - I was most interested! So, I placed an internet order and received the two kits (two turn-signals per kit) in 48 hours (none too shabby for a UK supplier to the Continent). Everything fit exactly as described. The whole conversion took around 30 minutes and I am very pleased with the results. Interestingly the conversion can work with or without the solid state flasher unit as the conversion has a huge 23 Watt resistor built into each circuit to emulate the load of the original bulbs. However if you want a pure LED conversion that lowers the load on the electrical system, the resistor can be removed simply by cutting its wires (example in the below photo). The flash rate is correct, the amber colour is correct and it is an EU street legal conversion. The only drawback is the ECU thinks I have a blown bulb so the dash light remains steady (indicating a blown bulb or a fault), instead of flashing in sympathy with the indicators. But a minor detail for a nice result.
