Check the bulbs they are double filamented with smaller being for brake lights
On a 1998 Isuzu Rodeo, the hazard flasher button is located on the dashboard, typically near the center console. It is usually marked with a red triangle symbol. Pressing this button activates the hazard lights, which flash all turn signal lights to alert other drivers in case of an emergency.
when all three of those lights turn on that means that your alternator is bad. i just went threw this same problem with my rodeo
Stock lights? If not, they might be drawing too much current for the relay.
remove the 2 screws from the red plastic and gently pry the red cover off.
Either the bulbs are burned out or the switch that activates them is not working. Also maybe a bad fuse
The Rodeo is made by a Rodeo
