Frequently Asked Questions Ask APW
Are headlights interchangeable between two different Toyota 4Runner generations?
Answer: Although a few DIYers have tried using headlights that are not specific to their vehicle's model and year, it is not advisable to do so for 4Runners that are often used for off-road activities. Since the headlight's housing, lens shape, and hood vary across models, using a headlight not made specifically for a particular 4Runner may be hazardous. Swapping headlights between different generations of vehicles can result in a loose fit and gaps in the housing. This is particularly dangerous because an ill-fitting headlight could easily fall off during bumpy roads and uneven trails. If the owner of a 4Runner insists on swapping headlights between generations, he must purchase a new housing that will accompany the headlight.
What's the main cause of foggy headlights?
Answer: The most likely cause of a hazy headlight lens is exposure to harsh weather over time. However, if the headlights are newly installed, the problem may lie somewhere other than dirt and grime buildup. In cases like this, check on how the headlights are installed. A bad seal on the headlight's housing can lead to accumulating condensation causing the lens to appear hazy. A loose Toyota 4Runner headlight bulb could also be the cause of condensation inside the lens. So have that checked as well. If both the headlight housing and bulb are installed incorrectly, bring the car to an auto shop and have a professional take a look at the headlight for a thorough inspection.
Why is it important to align the headlights of a Toyota 4Runner?
Answer: A misaligned headlight can render the light coming from it useless since it does not illuminate the right areas that will give the best visibility while driving. Headlights that are aimed too low would prevent the driver from seeing as far ahead as legally required (500 feet as per DMV laws). On the other hand, a headlight that is aimed too high can blind drivers of oncoming cars, which can lead to accidents and collisions. So to avoid such hazards on the road, always make sure that the headlights are properly aligned to give the Toyota 4Runner better visibility when driving at night or through poor weather.
