Finally, after few times doing push start to my car, then I decided to replace my battery. Bought NGS Volcano for Rp. 860k after discount and for old battery recycle. It is a maintenance free battery, but still it needs regular check up.
Since the battery is now so healthy, i think it was the right moment to install unused LED strips under the hood (I got some LED strips installed inside the car as well). So yesterday I installed them. It took me under 1 hour to install in my garage, because the hardest part was to open the front bumper.
I installed the wiring parallel with the foglamp (read this), so it will shine together.
