Do I recognize the brand on the lamp?

Do the Car Manufacturers use this brand. i.e. Has the product been subjected to exhaustive and extensive testing?

Do I believe the lamp will perform as the company claim. i.e.. Will I be able to see better in poor weather? Will it give me 30% more light?

How long will this lamp last i.e. Some makes will last more than 5 times longer than others . Is this reflected in the price?

60% of all road accidents happen at night. Will this product give me the security and comfort my family deserve?.

Are they value for money?

Have I chosen the correct technology for my driving demands i.e.Premium for Summer use and Allweather for Winter.
