Original BMW Yellow Bulb Socket for Amber Turn Signal Bulbs, E46 BMW 325i, 325xi, 330i, and 330xi (2001–2005)

This Original BMW turn indicator bulb socket holds and powers the yellow turn signal bulb in the indicator lamp of the 2001–2005 BMW 325i, 325xi, 330i, and 330xi. BMW names it the bulb socket, turn indicator, yellow. The color in that name is the key detail, because this socket is for use with an amber bulb only. A turn signal socket is the electrical connector inside the lamp assembly. It seats the bulb and supplies the contact that lights it when the signal is switched on. Each socket weighs 17 grams and is made in Spain, and BMW has supplied this part number since April 2000.

Original BMW Parts carry a 24-month parts warranty.

Bulb sockets sit in an exposed spot in the lamp housing, and weather can corrode the contacts inside them. A corroded or worn socket is a common reason a turn signal stops working correctly. In that case a new bulb alone may not fix it, and a new socket restores the electrical contact. Before you order, look at the bulb your lamp uses. An amber bulb points to this yellow-designated socket. BMW uses this same part number across a wide range of E46 3 Series cars with four-cylinder, six-cylinder, and diesel engines.

Common Questions

My turn signal only works some of the time. Can the socket cause that?
Yes. Poor electrical contact in a worn socket can cause an intermittent or dead signal. Corrosion or moisture in the socket can also leave the bulb dim or flickering.

Can I run a clear bulb in this socket?
No. BMW designates this socket yellow, for use with an amber bulb only.

What does a melted socket housing mean?
A burnt or melted housing comes from overheating or electrical resistance at the contacts. That is a sign the socket itself needs replacing.
