![]() You need an MSD timing light if your vehicle is of this type. A standard inductive light cannot give an accurate timing because they randomly pick any spark out of the multiple ones produced. ![]() MSD timing lights are a type designed to help tune engines on cars with multiple spark distribution systems. They usually include a toggle button for that purpose. Most digital timing lights can show RPMs as high as 9,999 and current selection between 2 and 4 cycles. Digital timing lightĭigital timing lights feature microprocessor-controlled circuitry and LED or LCD display for easy reading of RPMs and selection of a degree. Customer reviews can be helpful when looking for answers concerning accuracy. So, you need to check each and every product before buying. The accuracy of some adjustable timing lights in the market differs from brand to brand. An ordinary inductive timing light cannot do that when the engine speed increases and the distributor keeps changing position. That realigns the Top Dead Center ( TDC) mark on the balancer with the markings on the front cover. Adjustable/advance timing lightĪn adjustable or advance timing light uses a microprocessor to delay a strobe at a selected degree. Some timing lights under this category also have an in-built tachometer to monitor RPMs and a dwell meter that allows you to effectively monitor the time it takes to charge the coil. Another feature that we can mention is the button or knob used for adjusting the light to indicate different RPMs. This type of timing light can be used to tune the engine of two cycles and four-cycle motors. Inductive timing light features a non-adjustable Xenon light. The following are the popular timing light types you will find in the market today: Inductive timing light You need to know your engine specifications and choose the best product, considering its brightness, accuracy, durability, and reliability. However, different types in the market can be so confusing. 5 Best MSD timing light: MSD Ignition 8992Ī timing light is a crucial tool that every engine tuner should have.They all serve the same purpose but offer different RPM ranges, ability to operate a multi-spark system and offer features such as timing manual advance, a dwell meter, and the possible option to work on four-cylinder, six-cylinder, or eight-cylinder engines. What brand manufacturers offer automotive timing lights?Īutomotive timing lights come in three styles: inductive, digital, and self-powered. Not every timing light is compatible with MSD systems, so be sure to check that the one you want can meet these requirements before purchasing. To properly measure this sequence, the timing light must be able to show the beginning of the sequence. Typically, the distributor only provides a single spark for an ignition sequence, but in MSD systems, there are a series of them disbursed at a specific timing. How do timing lights help multiple spark distribution systems (MSD)? Units with a dwell meter measure for how long the coil is being charged and allow for prevention of pitting or burning due to an accurately set point gap.Adjustment knobs coupled with a tachometer allow for more precise timing measurement at different RPMs.Adjustment knobs that allow for the timing to be read at different RPMs are available on some models.It should be able to read both two-cycle and four-cycle engines. ![]() The standard timing lights come with a xenon light tube that is able to read timing when the vehicle engine is at idle.Knowing this allows adjustments to be made via manipulation of the distributor cap to make the spark plugs fire before or after the piston has reached the top dead center, depending on the malfunction or issue that needs to be fixed. ![]() By aiming this strobe light in the proper place, usually the crankshaft pulley, you will be able to read the degree markings on it, which are indicative of where the crankshaft is in its rotation and the respective pistons. Inductive timing lights, when connected properly to the cars engine and battery, detect the electricity every time the plug fires, and every time the plug fires, the timing light shoots a beam of light. The light is powered by the vehicle it is being used to test. The light can be a stroboscope that may use a simple neon lamp or a xenon strobe lamp that provides brighter light and better use in daylight or in shop lighting. Timing lights are diagnostic tools used to observe ignition timing in vehicles with distributors and are available as self-contained units or as a part of a more comprehensive engine analytical tool.
