The IAG Dome Light Bracket Kit allows you to easily install our IAG 4PC Interior LED Dome Light Kit with Harness (Part #IAG-ACC-F3150, not included) to a 4 Door Bronco with a OEM Hardtop. The dome light install for the 4 Door Bronco Hardtop differs slightly from the 4 Door Soft Tops and 2 Door Broncos. These brackets are included in our IAG-ACC-F3160 Dome Light Kit for the 4 Door Hardtop.
