Lexus GS Headlights Upgrade

Lexus GS is a full-size car sold by Lexus, the premium division of Toyota. The same car launched in 1991 as the Toyota Aristo in Japan, but the Lexus-badged model did not appear until 1993. Now in its fourth generation, the GS sold under the Aristo name in Japan only until the release of the third-generation model in 2005. Designed as a performance sedan competing in the mid-luxury class, the GS slots between the compact executive IS and large/flagship LS, and shares its chassis with one of Toyota's longest-running platforms: the S-series which has been used under multiple generations of the Toyota Crown premium sedans.

First generation

Italdesign Giugiaro (a design and engineering company) began the first design drawings of the GS 300 in 1988. The design firm aimed to produce a deluxe saloon which did without the numerous exterior features and detailing found on existing Japanese premium sedans, in favor of a more simplified, European-style appearance. The vehicle's exterior styling blended elements of the then-current Lexus LS flagship and SC performance coupe in a rounded, aerodynamic wedge-like shape which featured a high rear decklid and longer and wider proportions than rival vehicles.

1993-1997 GS 300 model required 9005 bulb size for high beams, 9006 for low and H3 bulbs for fog lights.

Second generation

In early August in 1997, the second-generation of the sedan was launched in Japan. A new front-engine, rear-wheel drive midsize platform was used. Lexus offered the GS 300 once again with slight modifications: 3.0-liter straight-six now producing 168 kW (225 hp) and 305 N⋅m (225 lb⋅ft) of torque. Taking into consideration customers’ requests for more power, the GS 400 was equipped with the 4.0-liter V8 that produced 224 kW (300 hp) and 420 N⋅m (310 ft⋅lb) of torque.

A facelift in 2000, for the 2001 model year was the only major design change of the second-generation GS. More interior wood trim was added, and steering wheel shift buttons were added to the GS 300. The V8 engine also received a 0.3-liter increase in displacement, so the model designation changed to GS 430 (Toyota type code UZS161). 1998-2004 GS 300 and GS 400 & GS 430 require 9006 (halogen) or D2R (oem HID) bulbs for low beams, 9005 bulb size for high beams and 9006 for fog lights.

Third generation

This GS generation was the introductory Lexus model for the marque's new L-finesse design philosophy, indicating the future direction of the Lexus lineup; it featured a fastback profile, retained quad headlights, LED tailamps, and one-piece bumpers.

Unveiled at the 2005 New York International Auto Show, the hybrid GS 450h (GWS191) joined the GS line in 2006 for the 2007 model year. GS Hybrid production started in February 2006. It was the first mass-production rear-wheel drive luxury hybrid car. Along with the new hybrid GS 450h, the V8-powered GS 460 offered the Active Stabilizer Suspension System for improved handling.

2005-2011 Lexus GS 350, GS 430, GS 450 and GS 460 models require all the same bulb sizes: 9006 for fog lights, 9005 for high beams and D4S for low beams.

Fourth generation

At its debut, the fourth generation model was shown in rear-wheel drive GS 350 (GRL10) form, powered by a V6 engine linked with a six-speed automatic transmission. Three driving modes are featured, ranging from fuel-conserving Eco to Sport S and Sport S+ which facilitate more sporty transmission shifting and engine throttle settings, as well as suspension damper and steering adjustments.

2012-2014 GS 350 and GS 450h require 9006 bulb size for fog lights, D4S low & high beams.

The revised GS debuted at Monterey Car Week in August 2015. Changes include a GS 200t variant equipped with the 2.0-liter 8AR-FTS turbocharged engine, and an update to the 3.5-liter V6, now upgraded to 2GR-FKS specification. Additional changes include revised exterior elements (including front and rear trim, LED headlights, wheels, and rocker panels), new active safety features, and a revised infotainment system.
