Osram NB or Philips XV is NOT 100% brighter than your stock bulb and I am 100% sure about this.

Pair of DEPO EK headlight is around 3.5 to 5k sa Banawe.

Remove your tint if you have one and get a clear tint, change your bulbs to NB or XV.

Sa budget mo na 1k, get the stock bulbs and DIY buff your headlights, meron ka pa sukli pang merienda.
