Changing the front headlamp light bulb for the first time...

Well, previously, I did replace the light bulb for the headlamp (low beam) at the service center that I regularly patron. That time it was the left hand side low beam light bulb that went off. Then, after my last major service, the right hand side low beam light bulb went off after 2 weeks. This time, instead of going back to the service center, I planned to see if I could buy it off the shelves from any car spare part shops. In the end I managed to get it, from a shop located in Suria Mas Sunway Damansara. This time, because I replacing it myself, it doesn't cost me that much money as I got the same replacement light bulb at nearly half the price of what I need to pay for at the service center. Well, can't really compare it in such a way since the nature of the business is different. At least it provides me with an alternative in case I really can't afford to replace it at the center during the regular servicing.
