First generation (2005–2009)
Second generation (2010–2016)
Third generation (2017-present)
The Buick LaCrosse is a mid-size sedan manufactured and marketed by Buick since 2004. The LaCrosse is now in its third generation, slotted above the Buick Regal as the brand’s flagship vehicle. The first LaCrosse was a rebadged variant of the Oldsmobile Aurora. The second generation moved to an entirely different vehicle, based on the Epsilon II platform.
The third-generation model debuted at the 2014 North American International Auto Show in Detroit, Michigan as a 2015 model-year vehicle. The new LaCrosse went sale near 2013 year-end and is now available for purchase across North America, Mexico, China, Australia, Turkey & South Korea through Buick dealerships.
At launch time, only one powertrain combination is offered: A General Motors Epsilon II 3.6 liter V-6 engine mated with GM’s 6T70 six-speed automatic transmission sending motive force exclusively to the front wheels.
LaCrosse was introduced into the Chinese market in 2010, where it is produced by Shanghai GM. It is available with the same 3.6-liter V-6 engine as in North America. A few months later, Shanghai GM announced that the second-generation Buick LaCrosse will be built and sold exclusively in China starting 2011, replacing the previous first-generation model which had been locally built since 2008. The plant manufactures sedans for both domestic sales as well as export to other countries including Australia, Mexico & North America.
How To Choose Correct Bulbs
The basic rule of choosing headlight bulbs includes knowing the three basic types of bulbs and understanding which one is best suited for your particular vehicle. Note that every car comes with its own kind of headlamp. There are three basic types: Xenon/HID, halogen, and LED. The vast majority of vehicles arrive in the showroom with halogen lights, while many high-end, newer cars have LED lights.
The third kind of light, xenon/HID (high-intensity discharge) headlamps is found only on very expensive models. The standard halogen headlights are frequently used because they provide adequate light for illumination, but you’ll find out that they won’t take you very far in terms of illumination during bad weather conditions like rain and snow. If you want to push your headlight’s performance beyond factory specs, then consider checking out high-performance upgrades first.
You can choose between different kinds of bulbs; HIDs or Xenons use gas instead of filaments to generate light while LEDs use semiconductors. LED lights offer superior performance characteristics like better energy efficiency and instant power at start-up, unlike other bulb types.
There are different kinds of bulbs, so you have to consider more than just the price when choosing the replacement bulbs. High-performance headlight upgrades come in three variations: HID upgrade, LED conversions, and Halogen bulbs. To help you pick the best option for your car among these three headlight upgrades, this article will offer a few more tips on how to choose headlights.
Rule of Thumb & Guide for Choosing Headlight Bulbs
The rule of thumb states that if your stock halogens work fine then don’t bother upgrading them since they’re sufficient enough for daily use. If however, your low beam lights are yellowish or too dim even after cleaning/washing them frequently then it’s high time you upgraded them with bulbs with better performance.
When the time comes to choose new headlights, make sure that you know how many bulbs come with your car’s assembly since the headlights use two or more light sources. Note that most vehicle models have one headlight with dual filaments for low and high beams. If multiple filaments are not present then stick to OEM (Original Equipment Manufacturer) replacement bulbs because they are designed for maximum output, which generally won’t be possible if you go for non-OEM units.
Note that although aftermarket parts are cheaper than OEM replacements, when it comes to input costs, i.e., maintenance/repair costs in the future, buying expensive lights doesn’t guarantee longevity just like buying cheaper ones don’t guarantee a short lifespan. If the headlight assembly itself is built from cheap plastic then no matter how expensive the bulbs are, they won’t last long because of poor quality housing.
To further help you choose better headlights for your car, here’s a list of benefits/advantages offered by HID lights over halogen and LED lights:
Advantages of HID Headlights
– More Lumens Output: The HIDs accommodate more light output or lumens as compared to any other type of headlights. In fact, it offers 3 times more luminosity than halogens and doubles that of LEDs. This means that your car can illuminate dark roads much more easily thereby reducing the risk of accidents due to bad weather conditions.
HIDs illuminate smooth highway roads better than halogens or LEDs.
– Long Bulb Life: Due to the lack of filaments, the HIDs offer a longer life span than any other headlight type.
– Quicker On/Off Response Time: The Xenon bulbs provide instant 100% power to your headlights, unlike the Halogen units which take time to warm up before reaching full brightness capacity. This means that you can quickly switch off and on your headlamps without delay i.e., it allows for night driving emergencies like avoiding high-speed collisions with wild animals crossing roads at night, etc.
Bulb replacement
So we gonna need for this you need a flat blade screwdriver which I have right here a socket wrench 10-millimeter driver and of course new headlamps oh you’re gonna want to undo this bolt and this bolt with the socket wrench and with the screwdriver flat blade screwdriver and want to pry this up a little bit so once you have those bolts undone you’ll notice that this black thing actually pops up I just had it up I want to move it up just apply it up a little bit same thing with this white tab pry it up a little bit if you don’t want to do you don’t want to grasp both headlight assemblies very firmly pull towards you as much as you possibly can you can hear some crunching maybe but I wouldn’t be too concerned about it just…
