View Full Version : Bulb Types

10-15-2004, 01:16 AM
Does anyone know the bulb types (turn signal, headlight, and brake light) that are on an 04 road king. I dont have my service manual yet and just want to make sure before I order LED replacements? Anyone had any problems with doing that? Know the best place to buy?

Thanks for your help

Hi Florida

They are 1156 & 1157

Just a thought before you go replacing bulbs with LED's, you will need the Badlands load equlizer to correct the darw from the bilbs to the computer.
Without them your turn signals, alarm & other lights will not work correctly.

You can get the just about anywhere

some of the bulbs have a differnt base on them know it is like a push in style and the 1157 and 1156 wont work i know for a fact that your break / tail light has the differnt bulb in it , also i dont think they make a led replacement for that yet , and if you take it apart you will see that the bulb can not be any larger then stock because it goes in from the back side and the size of the hole will not allow it to be bigger ....but wide is for sure right about needing the equilizer or the light mods wont work
