ok i searched on here an i thought i found the right size of speedo,tach and fuel bulbs. so i ordered the #194 led from superbright leds and they are the wronge size. my bulbs that came out have alot smaller socket size. just wondering if anyone knows the right size. my katana book just says 12v 3w. Oh and the title is wronge its a 1989 600 katana.
