The current economic climate means that you'd have to be very fortunate to not want, or need, to save money, whilst the current actual climate needs all the help it can get. That's why changing your car bulbs from halogen to HID or LED is a no-brainer and will be one of the best (and cheapest and easiest!) upgrades you can make to your car.
Whether we're talking about your headlights, brake or tail lights, indicator/turn lights or even your interior and dashboard lamps, all use energy and that's reflected in the amount of fuel your car consumes.
Clearly, saving fuel = saving money, so how do you go about it and what are your options?
Firstly, it's important to know the difference between the bulbs. If you're reading this, your car is probably already fitted with halogen bulbs as standard - these are lit by a filament and have a much higher power consumption than HID and LED bulbs. They are also not as effective and have a shorter life span, which is why switching to another light source makes sense.
