Independent Bulb Test Done Today.
I just finished running some tests of my own independent of the vehicle----
I took the bulb that was flickering and hooked it up directly to a battery and flickering was immediate.
I checked the supply voltage from the battery and had 12.7 volts.
The following times are not indicative of total times lite went out but rather just to see if intervals were changing.
5:00pm
I connected the bulb that was working good when I had them installed on the FX.
5:15pm
I checked the operating temperature of the bulb and got a reading of around 175 degrees.
5:38pm
First Flicker on and off.
5:41pm
light went out for 5 seconds and stayed on for 27.06 seconds.
5:44pm
light went out for 1.2 seconds and stayed on for 22.32 seconds.
5:45pm
light went out for 2.2 seconds and stayed on for 26.37 seconds.
5:47pm
light went out for 3.8 seconds and stayed on for 28.20 seconds.
5:51pm
light went out for 3.02 seconds and stayed on for 27.12 seconds.
6pm
light went out for 3.02 seconds and stayed on for 23.70 seconds.
I checked finish votage at 12.7 volts.
You get the Idea they are staying on for approxamately 27 seconds and the flickering off for around 3 seconds. At operating tempatures of over 170 to 180 degrees they seem to be overheating. And this was out in the open those temeratures would most likely be much higher in the confined space of the headlight area.
In conclussion unless the old style bulbs were shipped by mistake I am convinced there is still a problem with these bulbs being used for extended use over a minute or two at a time.
Let me apologize for this problem, I am currently having a tech from R&D figuring this out. I have a local FX35 coming in tomorrow to test all wattage problems and see what the issue is.
For all TL that uses 9005/9006 there is no problem. But I will sure get this fixed.
Other than this issue, a few more sets of replacements are currently being sent off. Will keep everything posted. Thank you. Again apologies for the flickering issues.
I would suggest that any bulbs to be are shipped be bench run for at least 45 minutes before shipping.
BTW I'm down two bulbs now.
