For the 2012 Hyundai Accent, the low-beam and high-beam headlights both use a 9003 bulb. The supplied fitment data does not list a headlight-type distinction, so use 9003 for both beam functions.
Front fog lights use an 881 bulb. Front turn signals and parking lights use 2357A, while rear turn signals use 1156A. The brake and tail lights share the 2357R bulb. Reverse lights use 921.
Center stop-light fitment depends on the body style: 921 is listed generally, while Hatchback models may use 2825 or 98. License plate lights and both front and rear side markers are listed with 2825 or 98 options. Interior lighting uses DE3175 for both the dome and map lights. Trunk lighting is listed as 2825 or 98.
