On many cars, the high beam bulb runs at reduced power during the day - check 'em and change 'em!
Small bulbs that burn out regularly - did you know you can replace these with LED lights?
White light when you back up - yup, they burn out and you can replace them with bright LEDs

Where is the battery located in a Buick LaCrosse?
The video above shows you how to replace the battery in your 2011 Buick LaCrosse. We recommend changing the battery in Buicks every 4 years. Although some batteries last much longer, most batteries begin breaking down chemically after four years, so you could experience dimmer headlights and other negative effects before you have a dead battery in your LaCrosse that you need to replace.
The battery location in a Buick LaCrosse can typically be found in the engine bay, but may be in the trunk, fender or inside of the vehicle. You may need to remove the air filter housing, a plastic engine cover or parts of the cowl to find the battery in your LaCrosse. See exactly where the battery is located in your 2011 Buick LaCrosse.
Replacing the battery in your LaCrosse involves removing the terminals. When you reconnect the terminals, your radio presets are likely to be cleared out. In some LaCrosses, you may need to re-enter a security code to get your radio to work again. Check for this code in your owners manual - it will usually be either a sticker or small card in the booklet. If you can't find it, call Buick and they will give you the code for free. In many Buicks, the transmission "learns" how you drive over time and makes adjustments, so you may experience altered driving dynamics as your car re-learns your driving style after changing the battery.
