Now that we have most of the critical safety items inspected, let's wrap up with a series of quick checks before hitting the road.
We're now in the final stretch of our checklist to make sure your vehicle is in good shape for a much-needed road trip!
First, position your vehicle head-first approximately 5 feet in front of a flat wall. Switch on all the exterior lights fitted to your vehicle. Flip the headlight switch to the "on" position and turn on the hazard lights. Alternatively, you can also move the turn signal stalk to indicate left or right - since we'll be making multiple tours around the vehicle, you'll have a chance to check the other side later.
Starting at the front of the vehicle, make sure both headlights are working and are free of any obstructions. Many vehicles also include front marker lights that are integrated into the headlight clusters - these are typically white or amber in color. Check the front turn signals (or whichever side you switched on using the turn signal stalk) for proper illumination. Note any bulb that isn't lighting up so you can replace them later.
- Check tail lights
The rear lights of a vehicle are the most complex, and it's very easy to miss an inoperative bulb here. Start with the tail lights; if the headlights are on, the tail lights should be as well. Here's where it gets tricky - the rear turn signal can either be on its own circuit or share the same bulb as the taillights/brake lights. It's pretty straightforward if it's the former, since the blinking turn signal can be seen switching on and off as normal. If it's the latter, the taillights will switch on and off in coordination with the turn signal.
- Check high beams
The following checks are best done with another person to assist, as it's not really possible to view the exterior of the vehicle when you're sitting in it. Technically, it can be done by using a brick to weigh down the brake pedal, but that's not exactly the safest way to go about things. Have your assistant sit in the driver's seat and hold the brake pedal. Turn off the hazard lights, then switch on the high beams. Moving to the front of the vehicle, check the headlights to make sure the high beams are nice and bright. These are aimed much higher than the standard headlights and are used to throw light much further down the road; consequently, they can and will blind other drivers if they're not switched off.
- Check brake lights
We'll check for a few more lights on the rear of the vehicle. As before, this part can get complicated depending on how your vehicle's tail lights are wired. All vehicles sold in the US starting with the 1986 model year require three brake lights - one each on the left and right side of the vehicle, along with a center high mount stop lamp (CHMSL, also popularly referred to as a "third brake light") located above the other two. Since your assistant is holding the brake pedal, all three should be illuminated. Make sure all of the brake lights are unobstructed (i.e. no stickers covering the housing) and readily visible from behind. Some vehicles are equipped with a "dual filament" type bulb, meaning a single bulb carries separate circuits for the tail lights. It's possible for one of the filaments to fail while the other continues to function. In this case, it will look like one of the brake lights is dimmer than the rest; alternatively, the tail light will be dark but the brake light will switch on as normal. If this is the case, the bulb needs to be replaced.
- Check reverse lights
This filter is typically located behind the glove compartment or underneath the dashboard on the passenger side. On some vehicles, you may need to remove the glove compartment door or an interior panel to gain access to the filter. If you haven't replaced this filter in a while, brace yourself! It's incredible how much junk gets caught on this filter over time: leaves, twigs, dead bugs, dirt, etc.

Note: If you've just detailed your vehicle, try usingdistilled water代替垫圈的液体以避免污渍和斑点。
