I guess this is a valid reason to upgrade to 12v? I can't find the 4019 bulbs anywhere for a reasonable price here in Canada. $16-$20 each US translates to $65 US each after shipping! I don't like being cheap but come on it's an incandescent bulb! I looked into led conversion bulbs but no luck since nobody makes them in 6v. It's pretty unfortunate since I was able to get the 6v charging system working (cleaned contacts in the reg) and there is a new 6v battery in it. Anybody know where to get some incandescent or leds in Canada that fit the 4019 housings in 6v? Thanks guys!
