Before ordering
Check the high-beam position, bucket and H4 wiring
Review Holley’s high-beam product details, then confirm the original high-beam position, 9–18V electrical system, H4 pinout, ground strategy, mounting and rear clearance. Some older Toyota applications require the H840 switched-ground harness.
LFRB121, LFRB141 and LFRB101 are high-beam-only products. The separate LFRB120-1, LFRB140-1 and LFRB100-1 models provide combined high/low beam and are separate products from the high-beam lamps offered here.
