    LED 1157 Tail Light Bulb, 1 Inch, Red
    (Part #91131022)
    x
                

    These LED tail light bulbs put out the light you're after, but don't get hot like normal bulbs. 1157 bulbs have staggered pins and 2 contacts on the plug. The bulbs appear to be clear, but are red when illuminated.

    LED taillight bulbs are quite efficient and use such small amounts of power that a normal flasher will not work correctly. The use of LEDs will almost always require the use of a special "low load" flasher like our 910-64110 (2-prong) or 910-64112 (3-prong.)

                MSDs High Current Relays are what you need to activate accessories that draw high current. These Relays are very reliable due to the fully automated manufacturing process and sophisticated coil winding procedure. The SPST High Current Relay is rated at 30 amps with an input voltage of 12 volts DC. The relay is ideal for use with the MSD RPM Activated Switch when 12 volts are responsible for activating a high current device such as a nitrous solenoid.The DPST relay is also rated at 30 amps with a 12 volt input voltage. This Relay is the best choice when 12 volts are required to activate multiple high current devices at the same time such as multiple stage nitrous solenoids.

    x
                If, after installing an MSD Ignition Control, your ta­chometer, fuel pump relay or electronic fuel injection (in foreign vehicles) doesnt operate correctly, your ap­plication may require a Tach Adapter. This is due to the trigger signal not being strong enough to trigger both the MSD and the factorys components.There are a few Tach Adapters available and for more information see pages 152 and 153. Each Adapter is simple to wire in and will have your MSD and vehicle firing away in no time! If you are triggering an MSD Blaster, 5, 6, SCI, or 7 Series Ignition with its white wire or points terminal, you will need the PN 8910 Tach Adapter. The PN 8910 will correct the operation of most voltage-triggered tachometers or fuel injection systems that do not work directly off the tach output terminal of the MSD Ignition Unit.
