aux light adjust

[Feejer/Weejer man]

I have some PIAA 1100x's on the bike from Cyclegadgets with their mirror mounted bracket. I was at a local motorcycle hangout and accessories store , and a guy who used to be a LD rider years ago, he was real knowledgeable, started explaining how to aim the light in a cross pattern and that these PIAA's had a directional beam that need to be mounted a certain way. Anyone who can understand this please advise on the adjustment and beam pattern. Thanks mike

Don't know about those, but any driving light has a tight, narrow beam that has to be carefully aimed for max benefit. I use a large door at work, measured off 25 feet, drew a line in the floor for future use. Bike on centerstand, high beams on for reference, and point. Took a few times to get them just right, first time was too wide and the damn road signs were blinding me. Tucked them in a bit and perfect. Don't understand why one would cross them, unless ditch illumination is the goal, might also alleviate some of the sign glare.

The reasoning behind the crossing of the driving lights is to fill in the dark spots when your leaned over at an angle. Say you are riding a tight right hander uphill and it's pitch black outside. The bike leans right, your beam headlight beam pattern and driving light on the right side also leans right, down into the ditch. This creates a black hole where your supposed to be looking... uphill. The left headlight and driving light are shining straight in front of you when leaned over, not looking uphill. If the driving beams are set to cross one another , the left driving light is now lighting up more of the road uphill, where your suppose to be looking.

Same thing applies in a downhill situation also.

Beam pattern is all related to how the lens is cut. Some lights can only be installed " right side up ", but some are OK with being flipped upside down.

thanks. Because of the brackets the light sere sideways. The guy I talked to knew about these and how to rotate them. So thats what I did and i will adjust the lights for the turns. Makes sense.
