They must be long as those 135w SOX bulbs. 60w SLI/H bulbs are probably long as 90w SOX bulb.

Usually I collect bulbs (Mostly LED) and some HID ones. I also own a couple of streetlights, but most are made in Poland.

However, I mostly prefer SOX bulbs. LED bulbs in their efficacy will never beat SOX bulbs, in my opinion.

Ok, what about the 60w SLI/H bulbs? Are they slightly longer than the 90w SOX bulbs?

Oh, so 60w SLI/H is as long as my 36w SOX-E bulb? Nice to know the lengths
