My bike's headlight has become weaker recently, making evening rides less comfortable on roads with poor lighting. I started checking the mini h4 bulb price in pakistan (https://shari.pk/product/mini-h4-bulb/), but I found that different bulbs can vary in brightness, size, power use, and fitting. I am now wondering whether price should be the main factor or if compatibility and beam quality matter more. For riders who have upgraded their bike's headlight, what should they check before choosing a mini H4 bulb?
