2009 Ford Flex Check Engine Light Flashing

I need to boost my lightly driven F-250 gas 6.2L Flex engine occasionally and this battery gets the job done fast (my battery is only rated for 650 cca so overkill in my case). I got the 3000A model to ensure I didn't have any problems jumping my truck or anyone else's as some family members have diesel trucks needing the higher amps. I will say, this product quite large, but that doesn't bother me as I know it'll have plenty of battery for whatever the task.

but it is unsettling to have the upstream light flashing

It is great to use Flex light with batteries. If you have a flex light this is a must!

The possibilities with this light are amazing. You should check it out.

I bought this and mounted it on my Ford Raptor. Works great!

This is a very nice headlamp, without two levels of white light, a red light and a flashing red light.  Having the battery pack on the back makes it much easier to balance and the straps are adjustable over a wide range.

Great size, love the built in light (it has flashing mode for some reason, just if you need to give someone a seizure on a film set?) I have always wanted this Porta Brace bag but kept talking myself out of it. I finally pulled the trigger on buying one and I'm glad I did. Sometimes I have a small lens in it if i am shooting an event with a smaller camera, but on a full set I kit it out with all the tools I'll need. for camera department. If you are on the fence about it, do it.

This flashing is amazing. The variable light settings to the strobe. No concerns on purchasing the light at all. I would love to give one to every person in my family. BUY IT YOU'LL LOVE IT!!!!

Very useful product because it is not like the regular flash. It has several functions that allow you to change such like: dimmer, lighter and even flashing. The flash level is used still not has a very strong light like regular flash. The image looks more nature light and hard to tell that is use flash or not.

With the press of a button-focus, zoom (variable), and flashing light showing camera is filming. It is so easy, light weight, hook up in seconds. This is a must have item. At the cost is inexpensive compared to the older version of this kind of equipment. Good investment and will make you smile.
