Why do only some models have the daytime lights?

I wanna know which models have the daytime lights (turn signal lights on) and if mine does not have them or use them.... can I change so they do come on or is there ANYTHING i can do to have them?

Easy install too!

 

sweet thanks man

 

So why do some vehicles have it and others don't?

or is that a Canadian truck thing?

 

In Canada it is a requirement to have DRL. Not sure about different parts in the USA.

 

Some trucks just seemed to have it installed. Maybe a location thing as well. I bought mine in AZ with no DRL and put them in myself.

 

When i bought my truck recently, it was a 40 dollar option

 

so i finally got to putting the damn things in but this flasher is huge and doesnt have the same connection as the previous one, which is way smaller. i didnt get a chance to check out where the relay goes before i started putting everything back together. i was a lil nervous disconnecting all this stuff but like u guys said theres really only one place for everything. any one have input on this, id really appreciate it. i checked the model #'s for both parts just to make sure and theyre both right.

 

x2.

 

so i finally figured out that the new relay has the connection for the previous flasher. but what about the 2nd connection on the relay. what happens w/that?
