In my G5, its turn signal indicator bulb in the speedometer stopped working and I needed to replace it. Did a search on the Forum where it was recommended to remove the headlight to access it -
http://www.enfieldmotorcycles.com/forum/index.php/topic,1611.0.htmlI fiddled around and found a quick and easy way. Stand on the right side of the bike just behind the handle. Keep the handle bar slightly turned to the left or straight. Look up at the
underside of the speedometer dial. It is a little hard to see it right away because of two reasons - there is a mass of jumbled up cables and wires and secondly it is dark there. First push the throttle cables to the left, and turn on a bright flash light to see the underside of speedometer dial.
Behind the speedometer cable, there are 3 round, black, cylindrical, rubber bulb holders attached to the underside of the speedometer. On the extreme left (on left side of bike) is high beam indicator, the middle one is for neutral indicator, and on the right side is for turn signal indicator. Use a long nose pliers to pull it out of its hole. It is a push-pull type bulb holder socket. Replace the bulb with 12 V 3 watts, BA 9 type bulb. Push it back into its hole and viola you are done. No need to remove the headlight.
In the picture below, the tip of the screw driver indicates the hole where the turn signal indicator bulb holder fits.
