On the 2nd-gen Tacoma this is one of the few genuinely easy jobs. Everything happens from the engine bay: pull the round dust cap off the back of the headlight, unplug the connector, release the clip or twist the bulb out, and put the new one in. The passenger side can usually be done by feel in ten minutes; the driver side is crowded by the battery and fuse box, and most people find it faster to pull the two 10 mm bolts along the top of the headlight and tilt the housing forward than to fight it blind.
The one thing people get wrong is touching the glass. Oil from your fingers bakes onto the quartz envelope and kills the bulb within months, so handle it by the base or through a glove. The second mistake is not seating the rubber dust cap fully - if it is cocked even slightly, water gets in, the reflector fogs, and then you are buying a headlight assembly instead of a $15 bulb.

The 2.7 2TR-FE and 4.0 1GR-FE use the same headlight housings and the same 10 mm mounting bolts, so tools do not change by engine. The real split is by model year: 2005-2011 trucks use a single dual-filament 9003/HB2/H4 bulb held by a spring wire clip, while the 2012-2015 facelift uses a separate H11 low beam and 9005/HB3 high beam that twist-lock into the housing.

Bulb types (9003/HB2 for 2005-2011, H11 low plus 9005 high for 2012-2015) and the 10 mm housing bolts are correct for this generation, but confirm your exact bulb number against the sticker or your owner's manual, since a few trim/market variants differ.
A single 9003 bulb, also sold as HB2 or H4, which handles both low and high beam from one dual-filament capsule. It is retained by a spring wire clip rather than a twist lock.
The facelifted 2012-2015 headlights use an H11 for low beam and a 9005 (HB3) for high beam as two separate bulbs. Both twist a quarter turn to release.
No. The bulb is reached from the engine bay through the dust cap. Many owners release a few grille clips and the two 10 mm headlight bolts to tilt the housing forward for hand room on the driver side, but the bumper stays on.
They physically fit, but the reflector housings are designed around a halogen filament position, so most LED bulbs scatter light, glare at oncoming traffic and are not DOT compliant for on-road use. If you want more output, a quality high-performance halogen like a Philips X-tremeVision or Sylvania SilverStar is the safer upgrade.
