Livingston: Lyndon Dykes & Hakeem Odoffin signs for Premiership side
Livingston have signed striker Lyndon Dykes from Queen of the South and Northampton Town defender Hakeem Odoffin on two-year-deals.
Dykes, 23, will stay with the Scottish Championship side on loan for the rest of the season, while Odoffin, 20, arrives now from England's League Two.
Livingston tried to sign Dykes last summer and say they beat off interest from other Premiership clubs.
"Lyndon is a good athlete and has a bit of everything in his game," Holt said.
"That's what attracted us initially. He can play numerous positions in an offensive role and we think we can make him better."
Odoffin is another who Livingston have been monitoring, with Holt explaining that the former Wolverhampton Wanderers player was a target for the summer.
However, the opportunity came about to sign the versatile defender - with a sell-on clause - this month.
"Getting the lad in this window will benefit everyone and allow Hakeem to bed-in and get a feel for the club," Holt said.
"We have had him watched on numerous occasions since he first appeared on our radar, and have received some very good scout reports.
Odoffin is predominantly a right back, but can also play wing-back and as a right-sided centre-back.
He joined Northampton last summer after being released by Wolves and has made 16 appearances in all competitions.
