3. Do consider converting meter bulbs, Turn signals etc to LED as they may save some power. However the gains will be only mild.
One thing I would like to add as per my experience :
When converting turn signals to LED, the bulb will (in most cases) not blink like the stock setup and will remain ON because of the power difference between the two. There is a seperate flasher module you'll have to add but since it is not used widely, getting a decent quality module is difficult. Plus, the LED bulbs you get for turn signals are forward-facing/focussed which means the reflector will not be used totally as in stock setup (the LED emit light outwards away from reflector) which effects its brightness. So it is better to stay stock with indicators. For meter lights, it is fine to switch to LEDs.
To give a better idea (to
bhvm) for more advice, the Activa in question uses a puny 3 Ampere battery. Instead of experimenting with turn signals, etc., judicious and careful use should be better to save power. I am against 55/60 in small two wheelers, LED headlight makes more sense without any need to save battery, etc. as the bulb uses lesser power than stock.
@
faisal_merchant I have worked a lot on 2013 HET Activa in the past years, if you need any advice in doing small DIYs which involve removing the panels, do let me know.
