Should swap the dimmed light bulb with your Subaru Forester instead of certain which lamp kind will match a socket? It often occurs that the established owner's guidebook (the only real legit method to obtain this kind of details) is not obtainable or does not include the necessary information to get a specific mod. Apart from that, we certainly have viewed frequently that headlights size may differ across Subaru Forester generations according to the mod and calendar year of manufacturing. Therefore we have put together an ultimate Subaru Forester bulb replacement guide to alleviate the pain of looking for the proper light variety and size for the interior or exterior lighting system.

Our Subaru Forester alternative graph retrieves the information through trusted light bulb manufacturers like Sylvania and Osram. On a single page, you will discover the OEM light bulb sizing to the Subaru Forester headlights, fog lights, tail lights, turn signals, side markers, backup lights, braking system lights, DRLs, dome lights, glove box lights, cargo area lights, etc. Just in case, you would like to upgrade the poor halogen front lights of your own Subaru Forester to an awesome LED or HID kit our company is here to suggest adequate upgraded solutions with proper fitment for low beam and high beam headlamps.

Headlights shouldn't be pointing up or down excessively when viewed from behind the vehicle. This is because this condition will reduce overall forward distance visibility at night and they'll tend to highlight road signs instead of what you're trying to see--which can lead to accidents! Directional signals are also more difficult to discern when headlights are canted downward so don't try this on vehicles that have factory-installed sequential turn signals where activation requires multiple movements for each signal. 

Check each of your 2003 Subaru Forester bulbs for alignment against the other side's light housing by looking at them straight-on from directly behind the car. The housings should have roughly equal amounts of inward or outward tilt so that their top edges are equally apart from one another, forming a V shape if you look at them crossways. If these conditions aren't met then there's likely an issue with the vehicle's suspension system that needs to be looked into further either by your mechanic or through your dealership service department since it could lead to reduced handling stability under certain driving conditions.
