Battery AH rating and LED lights and indicators

My 1979 z250 (electric start) requires a 12V 10AH (Pb) battery.I bought a LiFePO4 12V (6AH Pb equivalent).My question is:Is it possible (apart from starting) to reduce the amps/watts my motorcycle needs to operate by converting from incandesant bulbs to LED (headlight, indicators, running lighting) and possibly use this battery?​Should this be in a different subreddit?https://i.redd.it/7cj21mgnt9631.png via /r/CafeRacers https://www.reddit.com/r/CafeRacers/comments/c4kl7g/battery_ah_rating_and_led_lights_and_indicators/?utm_source=ifttt
