Dear Friends

Read my post carefully. I have a motor bike having 8.3A battery bike had 35Watt headlight which was pretty bad. I decided to connect car beam 100w/130w as my battery total power is 12 x 8.3 = 99.6 Watt so you know it can only provide 90% power to 100w point only. Now tell me should I connect another battery of same company in parallel for maximum brilliance of my head light or someone told me about connecting capacitor in parallel with my battery if capacitor is the answer then which capacitor will suits best or if battery is the answer?? you people know what I meant tell me now help needed.

If you used something like a capacitor it would not hold much charge. If you added another battery, it would hold more charge.

Your problem with adding extra batteries, is how they are charged. Your charger/alternator/dynamo is probably not powerful enough to maintain the charge in the batteries once you have turned your lights on. Using the additional battery will therefore give you initially brighter lights until it starts to lose its charge and then not being recharged by your motorbike fast enough, your lights will be as dim as they were before.

It must be small motorbike to have such weak lights and small battery. What is the model?

Edit a supercapacitor in parallel with a small battery can be useful for engine starting operations where lots of current is required for a very short period of time.

I have Suzuki GS 150CC with 8.3A battery It is able to light up 100/130 Watt beam of car with almost 90% brilliance but I want it normal light so should I add two 4700 uf capacitors in parallel with battery? will they increase the brilliance to full 100%

My bike alternator is strong enough to charge I think almost 15A battery It can do it easily

Wouldnâ€™t it be a lot better to convert to an led headlight?

The led can produce around 160 lm/w versus 35 lm/w for a typical bulb type.

100/130 w bulb can give you around 3000 lm at the cost of draining all of your available power and probably melting something down. A 25 w led can get you 4000 lm while drawing only 2.5 amps.

I report, you decide

My friend white LED light is never better for road I have tested it many times u know it only illuminates 3-4 feet better then all goes wrong for bulb or tube it rocks

Many costly cars also have bulbs I have installed sealed 7 inch beam

First off: If you didn't run parallel wiring for the new headlamp (or replace it entirely with heavier gauge) you are probably now in overdraw for the wires leading up to the headlamp. The wires will probably get VERY warm if you feel them after the lamp is on for 5-10 minutes. This is dangerous for several reasons, but mainly in that it will probably melt the insulation and eventually lead to a groundfault on the frame. Fix that if you are determined to have the higher wattage component over having a few lower watt higher lumen lights (like the LED systems others have mentioned). It' most likely the harness wiring that's the limiting factor on the light's brightness, as "just barely good enough" wire thickness is a standard fare on vehicles. It saves them money on every unit produced after all.

I'm unable to find the typical wattage of the stator on a Suuki GS, check your manual to see if it has that information. if not a multimeter  can be used to check it's current output. (pun intended) be sure you're producing enough to drive what you're intending to use. You should also fully diagnose the electrical system on the bike. It's very common for excessive ripple and "half dead" charging systems to go unnoticed for long periods of time unless you're a daily rider and a gearhead.

Capacitors in this application will not help at all. They will be a waste of time.

If your alternator can deliver 15Amps try a bigger bulb in. Or a different type of bulb.
