What is the number on the current bulb? You will have to take it out of its socket. It could be an 1157, 2057, 3057, or 3157, for example? There are LED direct replacements for each of these at Amazon, Walmart, Advance Auto, Autozone, and dozens of other sources.
The numbers above are for two-filament bulbs; dim for driving, bright for stop or turn. So you must also inspect the license plate lamp, High-Mounted-Stop-Light, and clearance marker lights, because each of those will be different. Make a shopping list.
