I've had KC slim lights fog light pattern 100watt bulbs an I use them at night for driving to work cause of the rural roads I drive on. I've only had them going on 3mths an both bulbs have burnt out already! Is this normal or do they just come with cheap bulbs.

If so any suggestion on a set of good bulbs?

 

Weird. Mine have been going strong for over a year with about the same type of use and my neighbors are 5 years old with a good amount of use, too. Bulbs are really cheap in price so just throw in something else and see what happens. Are you using the supplied harness/relay? And using a single battery?

 

Not normal, but the good thing is that they warranty the bulbs for 23 years

 

X2 email KC they will send you more

 

Yuuup used the supplied harness an relay provided also have the stock battery. I thought it was weird too for them to burn out like that myself
