FLX uses H7 bulb. 2 units each side for both low beam and high beam.
One unit of standard H7 bulb cost around Rm15 at spare parts shop. (Brand: Bosch)
The small light bulb only cost rm2-3.
If you can change it yourself then it is cheaper.
I just changed my H7 bulb straight away after purchase it at spare parts shop, parked in front of the shop.
Change front bulb price, for Saga FLX
