just like the title, what size bulbs do i need for my 99 turn signals, thanks

 

I can help with the outside turn lamps. They take a T20 (7440) wedge style bulb. I use the below LED ones in mine and they work great. I have LEDs in the parking lamp portion but someone else replaced these so I don't know their size. They too take a wedge style base but I don't know which one.

Front Turn Signal (for 99 spec bumpers)(www.superlumination.com)
Product ID: T20 Wedge
Product Name: Eagle Eye Tower
Attributes: Color - Amber Base - 7440 Single Circuit
Price: $24.99
Quantity: 2

 

parking lights are 194's

 

Not to complicate this but the bulb sizes vary depending if you have the OEM (Stanley) turn assembly or the "other" brands. For the OEM ones, use the T20 (7440) in the turn signals and the 194s for the parking lights.

For the "other" brands, still use the 194s in the parking lights but use a BA15 (1156) style in the turn signals.

Just swapped out my OEM units for an off brand and found this out
