The only right decision is the bulb of HB3 cap type and with base form P20d. You should keep up with Chrysler’s recommendation to put into vehicle headlights only 60 W capacity bulbs. In production of 2007 model year cars with engine code M664 the brand used high technology lamps. When you need replacing head light bulbs in Chrysler 300 5.7, make sure you install effective and strong agents. Safe drive at night on Chrysler 300 is possible with working head light only. Every lamp in Chrysler cars with motors 6.1 has limit age, anyway. Especially lamps for 300 with plus capacity and 12 V voltage may be broken soon.
Installing P20d lamp by yourself can be hard for 2009 300 owners. The needed cap type should be only HB3, otherwise Chrysler made in 2010 won’t take the bulb. Don’t try to take headlight in 300 to pieces – holder in 5.7 motor cars is easily relieved. Though you may choose more than 60 W of real output sticking to lamps with 12 V voltage.
It’s easily bad idea for 2007 Chrysler owners to buy other than HB3 type bulbs with base different from P20d. By taking the bulb holder in 300 cars with 6.1 motor be careful not to destroy it. Remember that any lamp is 12 V of voltage, power level on the pack is 60 W only. If you keep up with all the rules, 2005 Chrysler 300 headlights will serve you much more.
