Unfortunately, the standard timing lights that are available under $50 may or may not feature the dwell, tachometer, and other advanced functions. You need to consider your requirements when investing in the timing lights. The product that comes equipped with the advanced options can help you get a clear picture of your engine’s timing. The only issue is that these modern models can cost you as much as $240. So, if you have the budget for an advanced timing light, then this can be a great addition to your mechanical toolkit.
