Hearing your turn signals... If hearing the flasher is problem, you could try this: get cheap 5 inch, 8-ohm speaker, like a car door stereo speaker from the boneyard. Solder a 16 ohm, 2 watt resistor to one lug, and a ground wire to the other. At the other end of the resistor, solder a pair of diodes, 1N4004 would work, with the arrows pointing toward the resistor, to make a "Y" . From the free end of each diode, run a wire to one of the dash telltales for the flashers. That should give you "thump/bump" sound with each flash, with about 2 watts of audio power behind it, which is quite a lot. Sort of like a rap music bass line. If the sound is too loud, you could increase the value of the resistor. The diodes prevent one telltale backfeeding the other, and crossing the flashers up. You could also try shunting the speaker with a low-value resistor, say 0.5 ohm, and put the whole mess in series with the power feed line to the flasher. Gordr - SDC forum - Nov 2010
