Life span of these blubs vary between 1 year to couple of months (the general rule of thumb is the brighter and hotter the bulbs are the shorter their life span), despite that nothing has prepared me for my next encounter which only last a mere 20 mins!
I went and bought a T10 led with 10 led from a "famous" accessories shop along old klang road yesterday. Despite hard negotiations, I only managed to get the pair for bulb for RM70. Despite its shoddy look, i decided to give it a try. The shop's one of many unskilled workers went ahead and installed the T10 led.
Nightmare begin 5 hrs later, when i found the one of the bulb has actually burnt off, and pieces of it has melted and stuck to the headlight reflector, and I decided to remove the other bulb before that bulb melts away as well, unfortunately the bulb wasn't fixed properly to the socket, so the entire bulb fall into the headlight. Now comes the interesting and grueling part of removing them out. Basically I had to remove the headlight, and take off the main bulb and shake the bulb out. After a good 30 mins both the bulb and pieces of the bulb were removed. But it certainly have left a burn scar on the reflector.
Conclusion: The bulb which was sold to me, is below sub standard and the workers at accessories shop was certainly unskilled. I certainly wont be returning to that particular shop in this life time or the next. Anyone who wants to replace their T10 bulb, I would strongly advice to source for good quality (Taiwan, japan or even us made).
